The ACT stands for the American College Test. It was designed to gauge if students would be successful in college in a way that would be reliable. To be able to read quickly and accurately, to have English skills needed for written communication, to be able to interpret data, to have attained a certain level of mathematical understanding – these are concepts measured on the ACT.
Ultimately, the skills measured on the ACT matter for every job and career that exists. A student with strong skills is positioned to achieve. In addition, a higher ACT score can open the door to more schools, better schools, direct admit into college programs, and potentially to tuition breaks or scholarships.

ACT Advantage recommends taking the ACT 3-4 times, planning for March to be somewhere in the middle of that sequence. The ACT is free when taken at school, but you’ll register to take it on www.act.org for the other times.
"I was pleased that I hit my goal on my first test after taking ACT prep with Lauren Bartel. Her classes aligned exactly with what was on the test, and everything she taught helped me be successful. I am glad I took this prep, and it wasn't even at my school! "
“We registered our son for ACT Bootcamp @ Arrowhead HS in February 2024. The efficient delivery of information in one session made it more tolerable and less daunting for our reluctant son. He left bootcamp with many applicable strategies as well as additional practice materials, saying it was a worthwhile experience. The tips and methods were especially helpful for him. We are pleased that on his first attempt at the exam, he achieved his goal score. Highly recommend!”
“I took the ACT bootcamp at Arrowhead a week before I took my first ACT, and I truly believe that it helped so much! My score improved from 21 to 29. "
"The coaching helped me in ALL areas of the ACT. I learned the ins and outs of the Reading, Science, and English. It helped me be a more efficient reader for the ACT, annotating clues as I read. I learned all about grammar and punctuation rules which helped improve my practice English ACT score to my real ACT score dramatically. I was shown how to work around the Science section with speed and accuracy. This not only helped my scores on the ACT itself, but these skills I could translate into my classes in school as well. I recommend anyone to take the ACT bootcamp--- especially those willingly and wanting to learn to improve their overall academic knowledge and also to improve their ACT score."
"I was so happy that my daughter attended the AHS bootcamp. She goes to Brookfield East, but I had heard about Lauren from my neighbor.
My daughter's composite score was much higher than anticipated, and it motivated her to want to test again in June. We believe it was because of the bootcamp. I wish this existed for my other kids because it was very helpful. Thank you to Lauren."
"I am so glad I took Mrs. Bartel's bootcamp because I knew what to do in English, Reading, and Science. I scored 31, 35, and 36 after taking prep with ACT Advantage. I had strategies that helped me do much better than my friends. I even started using what I learned in some of my classes. It was worth going to, and I think all juniors should go."
"Lauren's coaching in February before the state exam helped me achieve incredible scores. I grew in the places I needed it the most, earning an outstanding composite score. I am eligible for scholarships because of my ACT score. I highly recommend ACT prep to other Arrowhead students."
"My daughter participated in one of Lauren's bootcamps and it was such a positive experience for her. She was pretty stressed out after doing the practice ACTs through school, but during the bootcamp and in preparation for the actual test, Lauren gave her some really easy-to-execute and easy-to-remember strategies for what to look for, and how to get through the test efficiently."
"I scored a 35 composite after taking test prep with ACT Advantage. These classes were not at my school, so I am so glad I found them. I am going to test again to get that 36. I am already able to get many scholarships because of my score. "
“Over the summer, I worked with Mrs. Bartel, prepping for the ACT. Her expertise not only boosted my confidence, but the strategies she taught me for the English, Reading, and Science sections proved very helpful. These tips and tricks she shared didn’t just aid me in those specific areas but on all four tests, resulting in a significantly higher score than I had anticipated. I’ve integrated her testing strategies and skills into my regular study routines and have been utilizing them on my regular school exams. Forever grateful for her impact on my academic journey!”
"Mrs. Bartel’s ACT coaching in English, Reading and Science helped me tremendously! Her coaching not only gave me confidence going into my first ACT test but increased my scores! I went from a 23 in English to a 30, and I went from a 30 in Reading to a 34. My Science even went up to a 27. The tips and tricks she gave me to excel in the ACT have continued to help me in my AP literature class. Mrs. Bartel gave me many practice tests to take home, guided me in finding the correct answer and thoroughly explained why the answer was correct. Having her guidance prepared me for the many ACT tests but also my academic coursework. I was directly admitted into college nursing programs and received scholarships because of my scores. Highly recommend Mrs. Bartel!"
“Mrs. Bartel helped me not only improve my ACT test scores but my test taking skills in general. Her testing and study ‘hacks’ for English, Reading, and Science have been helpful in college. The methods she taught me have been integrated into my academic routines and her academic coaching made me a more successful student. She found strategies that fit my unique learning needs. I am forever grateful how passionate and patient she was while she was coaching me. The skills you learn while working with Mrs. Bartel will be utilized throughout your academic career.”
“Working with ACT Advantage was a game-changer for both of my children. Highly recommend! Their scores were optimized with this prep, scoring a 30 and a 35. I am immensely grateful for the positive impact. Do not waste your time with anyone else. ”
“As a parent of a child that struggled in school and has bad test anxiety, we were very concerned that the ACT test would be overwhelming. We started working with Lauren two summers before she had to take the ACT and her work with Lauren paid off. First and foremost, Lauren leverages her years of teaching experience to gather an understanding of the student’s strengths and weaknesses. Then, she applies that understanding to the training program that she develops which involves both the student and parent in the process. I have recommended Lauren to many people and continue to do so.”
"I didn't need any Math help, so Lauren coached me specifically in English. She helped me go from 18 to over a 30 in just a few sessions. She helped me by teaching me the basics in English I did not know. This was huge in helping me earn a substantial scholarship. It was very worth the time and obviously worth the investment. Everyone should be coached by her."
"The ACT advantage classes helped raise my confidence for the ACT by going in depth on specific questions, teaching practical and convenient strategies, and giving real ACT tests with questions that were actually used, all to give me a better understanding of what the ACT will really be like. Besides, none of these practices to prepare for the ACT were taught in my school classes. I’d recommend these courses to anyone.
"Mrs. Bartel teaches strategies that make students successful. I took her summer class after my junior year, because I knew I could do better than I had been. I am thankful she coached me in English, Reading, and Science, helping me improve my composite score by +10 points."
"Mrs. Bartel’s ACT academic coaching has helped prepare me greatly for the ACT. I came in with little knowledge as to how the ACT was run and formatted but her tips and strategies helped clear that all up for me. Learning the strategies for English, reading, and science have also strengthened my overall knowledge of the topics which has raised my confidence for taking the ACT. I would recommend these classes to anyone who has doubts or questions surrounding the ACT because Mrs. Bartel clarifies them and helps develop you for such an important test."
"This class helped me learn different strategies and shortcuts that helped me get to the answer really quickly and effectively. I am able to pick out the strategies I need to know different types of questions on the ACT. This class definitely gave me a lot of insight into what the ACT will look like and how I can do my best. I feel much more prepared for the ACT than before and I think this class helped me not get so stressed and anxious when looking at the questions. I am confident."
"In person sessions helped me to efficiently answer questions with useful strategies. My friends even asked me what I’ve been learning. My scores from even taking practice tests have improved from the spring. I feel more comfortable and confident taking these tests. The strategies we used helped with reducing the amount of time it takes me to take a session. The rules like English with punctuation and choosing the most concise answer, repetition helped me. My first ACT score was in the 30's, and all my friends wish they took this class."
"The teaching method is very effective in this class. I liked that we actually got to do the ACT tests and learned why certain answers were wrong in addition to what was actually right. I liked working with Mrs. Bartel because she is very helpful. It’s important to know that the homework and extra work helps you a lot. The coaching is worth the extra time and money because it prepares you very well. My English and Reading scores were in the 30's after taking a summer class."
"My son took the 2025 summer classes with ACT Advantage with great results. For example, he took his English score on the Pre-ACT from a 25 to a 33 on the actual ACT after coaching. We are so happy. He credits his prep classes with helping him identify patterns in questions and in identifying patterns in what questions are actually asking. We are ecstatic with his composite score."
“The test prep at my daughter's school did not make an impact on her score. I heard about ACT Advantage from a friend and was able to get her in those classes. Ella raised her scores +7, and I am so thankful that. "
“I can’t say enough about our experience with Lauren’s ACT academic coaching. From the outset, she communicated clear plans and strategies tailored to my daughter's needs, instilling confidence and direction in her ACT preparation journey. The results speak volumes about Lauren's expertise and dedication. Thanks to her guidance, my daughter's ACT scores significantly improved. In addition to her remarkable professional abilities, Lauren's supportive and encouraging demeanor fostered a positive learning environment where my daughter felt motivated to excel. Her personalized attention and genuine investment in my daughter's success truly set her apart.”
“My son Sam was not a naturally gifted test taker and was a hands-on learner, requiring more than the online ACT prep course work. Lauren provided great prep and test taking strategies that allowed Sam to surpass his predicted ACT score and the goal we had set. Her coaching and instruction ensured knowledge and skills Sam would need for years to come. I believe this carried him forward as well as he completed his undergraduate and sat for his GRE. Sam indicates that he continues to use the test strategies he learned with Lauren even now as a 2nd year Doctor of Physical Therapy student.”
“I highly recommend Lauren Bartel who academically coached all my four children from 2016-2022. Each child greatly increased their scores with her help. Lauren was a great resource for learning test-taking strategies for each part of the ACT test, teaching actual concepts as needed. My children gained the most value from the Science, English, and Reading sections. Lauren is very organized, thorough, and relevant in what she teaches. She provided each one with independent practice to do in between sessions and worked to ensure their success in a timed environment. Her communication throughout the process with both myself and my children was outstanding.”
“Our son Charlie took both the Math and Reading/Science/English prep classes with ACT Advantage. I am happy because he learned so much about test taking and raised his scores from the low 20's to a 29 composite. I recommend them highly. ”
“Both our son and daughter made huge improvements in their ACT scores after being coached by Lauren. She not only coached them through the academic parts of the exam, but also on test taking in general. I would highly recommend her as both our kids got into colleges they wanted and both received scholarships based on their ACT scores.”
“We hired Lauren Bartel as our children’s ACT coach the summer between sophomore and junior year to help them better prepare for the unique content and structure of this challenging test. We assumed that they would repeat their coaching sessions during their Junior year, but both our children said they felt confident and they practiced with their materials provided that they didn’t need more sessions. We figured that they would need to take the ACT several times to achieve a desired result. They scored a 28 and 32 respectively on their first attempts and were happy with their results. You won’t be disappointed with this investment."
“My son tried prep with another testing place but didn't get results. He said that taking a lot of tests didn't help and was disappointed that he wasted time. Then in January and February, attended some prep at Arrowhead, and his March scores went way up. He thinks that was because of the tips an teaching from his different prep teachers. I think other parents need to know that some test prep is better than others."
