I'm a high school graduate from Arizona, and I am so happy to be here! So far, I have passed 15 AP exams (US Gov, CSP, Lang, Euro, Calc AB, Comp Gov, Biology, Chemistry, Physics 1, Lit, French, Statistics, US History, Seminar, & Research), scoring a 5 on 13 of those exams and a 4 on the other 2.

If you have any questions on any of the aforementioned APs, or on the SAT/ACT, please feel free to reach out!:)

Upcoming Sessions

Pomodoro Power Hours 😎

    6th session
Welcome everyone! These sessions will be 2-hour sessions with four 25-minute study intervals. During this time, everyone should focus on their tasks without any distractions. Once the 25 minutes are up, there will be a short break for 5 minutes. Participants are encouraged to relax, stretch, or grab a drink. Throughout the study session, there will be a supportive environment where participants can ask questions, share progress, and discuss challenges. At the end, there will be time to recap what was accomplished during the study group and share any feedback or suggestions for future sessions! NOTE: - Times may change - More sessions will be added as time goes on - I will end the session if no one joins within the first 15 mins

Thank you for hosting such a fun session! It truly helped me relax after a long day of APs and cleaning, and I really enjoyed talking with everyone!

This session was very helpful and included a lot of subjects that I have been struggling in, and so I was able to understand them a lot better and how the questions need to be set up. I also appreciate that you took the extra time to go over the requested questions.
