I did AP Calculus AB and AP Physics C: Mechanics with Option Training Institute in the 2019-2020 academic year. I did not have the Calculus knowledge required for Physics C: Mechanics, but my trainer patiently taught me all the basics required. I was taught every concept clearly and my trainer only moved on once I was 100% sure about each concept. I was given weekly extra materials and homework to increase my practice. After I completed the material I was given many past papers as mock exams and then my trainer and I went over them one question at a time which was very helpful and gave me great clarity. Before my exam, I was feeling very calm as I felt very confident about the material and I finally scored a 5 in both AP Physics C: Mechanics and AP Calculus AB.
