true that AP courses are advance, but bro Pakistan's tests are really weird...its all about memorizing every single thing in the book and then write it on tests...very limited mc questions if any. For those who haven't took APs then its not an easy thing to ace Fsc becuase high school science courses in US don't cover every thing. fsc is almost like college stuff. On top of this in pakistan problems are approached differently. In US they make it easy 4 us with reference tables, scientific calculators and problems are solved in a simple way...ask your parents to tutor you and you will experience this. Remember one more thing when studying....Ap bio focuses more on genetics and process of resipiration sort of things. fsc focuses on body in detail.
