The Complete Guide To Digital SAT Math Is Here!
The best and most complete SAT Math book
ever written (at least we think so).
In 2024, the SAT is now a brand new Digital SAT. Our brand new Ultimate Digital SAT Course and our Digital SAT Math Book are now available. We have re-filmed our entire course and rewritten all of our books for the Digital SAT and our own digital practice tests that are reflective of the difficulty students see on test day. The Digital SAT is a HUGE change to the SAT, so old paper SAT practice tests and books will not properly prepare you for the Digital SAT.

The best and most complete SAT Math book
ever written (at least we think so).
“Matt was a wonderful resource. He listened to my son about his strengths and weaknesses and then used their practice tests scores to give them insights on how to improve - not formulaic at all. He was patient, encouraging, and honest with his communication about performance and progress. Matt got my son to to perfect and near perfect SAT scores in less than 5 months. We are so impressed with his demeanor and teaching style.”
- Sandra W.
"Michael Stroup was the perfect SAT tutor for my daughter who actually looked forward to her Thursday evening SAT tutoring sessions (who does that?). Michael came in with a very clear plan that made sense in the months, weeks, and days leading up to the actual test. Michael was kind, funny, and was able to speak to my daughter in a way that really resonated. I am so grateful that we found PrepPros. I really can't imagine my daughter having close to the amount of success had we gone another route (self-study or group sessions). Having individualized, 1:1 training is definitely worth the investment and PrepPros is by far the best SAT tutoring out there!”
- Michelle W.
“I highly recommend Matt and PrepPros. Beyond knowing test content and strategies, Matt was really easy to work with and schedule, quickly assessed my son’s strengths and areas to work on, and made efficient use of his time and my son’s at each session and with homework. It’s also not a cookie-cutter approach…I went in thinking my son would take the SAT and instead Matt dug deeper into my son’s sample test scores and recommended that he take the ACT. We’re grateful for Matt’s wise advice, as my son improve his ACT score by 6 points and is happy to have his standardized testing behind him after one sitting!”
- Joyce R.
“If we could give Mike 10 stars, we would! He was fantastic! With Mike’s help, our daughter improved her test-taking skills dramatically and gained the confidence she needed to make significant improvements each week. Mike was very professional, prompt, and used every minute with our daughter to maximize her results. We could not be any happier with the value that Mike provided!”
- Cassandra L.
“My son worked with Mike and had an excellent experience. Mike knows the material inside and out and knows how to help the student. His instruction is most helpful, very much to the point and my son's scores improved dramatically. Mike was a pleasure to work with, always on time and very professional and friendly. My son enjoyed working with him very much. Thank you Mike!”
- Brianna P.
“Matt has helped all three of my children move their scores from 2 - 5 points on the ACT. Those of you reading this review who have already started down the college path KNOW how significant even ONE point can be. Somewhere I am sure there exists a dollar spent/point raised matrix - if Matt was part of this study, he would be at the apex of the curve. If you are looking for concise, value-added test prep look no further than Matt and the PrepPros business.”
- Dominique B.
“After a poor first result on her ACT, we hired Mike to help our daughter increase her scores. We are extremely please with the improvement that PrepPros helped her achieve on her test scores! They helped her get into a top private school for her college experience. Michael came up with a plan and was on time and very easy to work with. Highly recommend this company. Wish we had started before the first exam!”
- Tim M.
'“Matt Stroup was an excellent tutor for my daughter. She raised her score 8 points from her pre-tutoring practice test to her actual score on the ACT. Matt always came in with a plan and the hour was well spent. I highly recommend Matt and PrepPros!”
- Gwen S.
“My son had a 27 on the ACT when he started with Michael Stroup. We just got his most recent test scores and he is up to a 32! Michael is great! He is very personable and he offer flexible scheduling, even on Sundays. Thank you!!”
- Tammie S.
“My son’s SAT score dramatically improved (over 250 points), his confidence soared and, going forward, he has a confidant he can turn to for any academic situation. We were just lucky to find Matt, whose calm and reassuring demeanor went a long way. Our younger child is on deck.”
- Thomas F.
“Sometimes you think twelve times before spending additional funds on top of what "we" already have to spend for survival, sports and life. PrepPros is an absolute, no questions, no issues, 100% yes. Excellent support, communication, knowledge with the ability for common sense and personal input. Priceless. Believe in the system. It does work. Michael Stroup is great!”
- Sandra N.
“Matt was an amazing tutor for my son and help him score a 35 on his first ACT! The tutoring sessions are organized and extremely productive. Matt takes time to go over topics that are causing students difficulty and focused in on exactly what my son son needed help with. Matt was an invaluable resource, and I will use him again when my other children need ACT/SAT tutoring.”
- Savannah P.
“I took the 1400+ SAT Class with Mike and definitely credit the class with my success on test day. My score went from the upper 1300s on practice tests to the mid 1500s on the real SAT! The class was a combination of strategy, test practice, and review of material that may not have been covered in school. Mike also kept the class fun, so I really enjoyed the SAT class each week.”
- Dylan M.
“I had an amazing experience working with Matt in the 30+ ACT Class. Prior to the class, I struggled to get above 27 in most sections. I am proud to say that my composite score increased by 5 points, and I was able to score a perfect 36 in both Math and Science. This class truly does offer many benefits and proved a game changer going into college admissions. Definitely recommend the 30+ ACT Class to anyone looking to increase their ACT score!”
- Ryan M.
“Mike did a great job with out daughter. In just 6 weeks, he was able to help her learn the skills to boost her SAT score 160 points! He was patient and supportive, which helped reduce her anxiety. She is thrilled to get into her first choice college and get the needed scholarship money.”
- Devon S.
“After my son got a 25 on his first ACT, I enrolled him in the 30+ ACT Class. The class is very thorough and covers everything you need to know to improve your ACT scores. With the class and homework, he improved his practice test scores by at least 1-point each week. After the 30+ ACT Class and a few private tutoring sessions with Matt, he scored a 33! This score is going to help so much with scholarship opportunities! We are a large family with modest means; having said that, this was money well spent.”
- Kelly A.
“Now that the college admissions process is coming to a close, I am reflecting on the support that was most beneficial. Mike helped my son achieve a near perfect SAT scores. His temperament and expertise helped immensely. My son was motivated to do the preparation work for the sessions and felt more confident after each session. I highly recommend PrepPros!”
- Julia C.
“As a working Mom, finding great ACT Prep is very challenging. I signed up my daughter for the 30+ ACT Class and was thrilled with the results. After taking the class, she got a 32, higher than all of her practice test scores. PrepPros30+ ACT Class made my daughter score even higher than her goal. There’s no need to pay more money for private tutoring or longer classes if Matt can give our kids their dream ACT scores.”
- Linda S.
“We had an exceptional experience with Matt. Our son had an ACT goal, and Matt helped him exceed his goal. The improvement in our son’s score has opened up doors for him and turned a few reach schools into match schools. Just a great experience and great results!”
- Min Y.
“Mike was awesome! Very accommodating and easy to schedule with. He worked with me to prepare for the ACT exam, and his help made all of the difference in my score!”
- Hillary S.
“Matt is amazing! My daughter is dyslexic and standardized testing has never been her strengths. In addition to reviewing content (which he knows inside and out) and providing materials, his strategies for approach the ACT helped her bump her score a significant 4 points. He’s friendly and his teaching style put her at ease during tutoring sessions. We will hire him again when our son is ready. Highly recommend!”
- Jennifer D.
“Our child’s score increased by 3 points to a 34 after expert tutoring with Mike! Mike was professional and great to work with. He was able to adapt to our child’s learning style. His study methods and lessons were extremely effective, and we are thrilled that our daughter is one-and-done with the ACT! Hard work and dedication by the student under the guidance of PrepPros is for sure a proven way to prepare for the ACT”
- Stacey L.
“Matt helped my son raised his SAT score 200 points through private tutoring sessions. Matt was great at knowing his strengths and weaknesses and customizing a plan to increase his score. He help him with time management strategies and taught him how to approach various questions by looking for key facts, words and phrases, and applying rules. He was able to compensate for his average English skills by getting an almost perfect math score. This is not a one size fits all tutoring program. We are so happy with his SAT score and highly recommend.”
- Tina C.
“Mike was absolutely phenomenal with my daughter. He was very good at explaining and simplifying the ACT. I could see my daughter’s confidence growing with every practice test. From her initial diagnostic to her second ACT, her score increased by 6 points. The most dramatic gain, however, was in the science, which jumped a whopping 11 points!”
- Rich B.
“I can’t say enough about Matt. He has tutored both of our sons, and we are astounded with their ACT scores. Our oldest son scored a 34 and our younger son just scored a 35. I have personally referred Matt to countless friends and everyone has been pleased with his commitment to his students and his ability to get them to their full potential. I cannot recommend Matt strongly enough!”
