My son scored an 800 on the SAT Math II and a 5 on the AP Stats! Thanks to Carnegie Prep for all of the test prep support!

Hey Marshall,
I thought the test went better than I expected it to be. With math, I felt like I knew how to approach every single question I saw. I believe 9 out of your 10 hints were on the test. The only thing I didn’t use was the hippity hop (I was upset no bunny). But I think the extra helps and just doing as many problems as I could really helped me.

Dear Austin and Marshall,
I decided to take the SAT again in May because I thought I could improve my math score. I got my score back today – 2400! I am beyond happy, and wanted to share the good news, because all of your help made that score a possibility. I thank you for helping me achieve the perfect score! Thanks so much.

Hi Marshall,
C. got a lot out of the class and really enjoyed having you as her teacher. She says you are “funny, awesome, a great teacher”! Just thought you should know. Thank you for all your effort.

Thank you thank you! My daughter so loved the ACT Blast with Peter and Marshall! She said that she understands now how kids who take a course have such an advantage over those that do not. The strategies she learned she could not get from a book or through practice on her own.

I have great news! I have accepted my admission to Yale’s Class of 2020! I am very excited about this, as I know Yale is the best fit for me. I can’t thank you and the other Carnegie heroes enough. I really couldn’t have done it without each and every one of you. John, Rick, Marshall — you guys rock.

Just finished up the [PSAT] about 15 minutes ago and it went awesome! I remember taking it last year and felt overwhelmed with the timing and number of questions I was required to answer. The course definitely prepared me to be a better test taker. Looking forward to getting scores and sending them your way!

Hey Marshall –
I felt really confident on the math sections. The easy problems were really easy, and the harder ones were extremely manageable. Thank you so much for all the help these past 10 weeks! There was one question in particular that I looked at and immediately felt bad for kids who didn’t have you and wouldn’t think to plug in numbers.
