i had A in o level chemistry plus in all sciences...
i had A in o lvl combined science
i had 730/800 in SAT II chemistry
i had B in AS chemistry....
i retake it dis year, do a healthy paper 3 and 5 and
do a good paper 2, apart that the only mistake i did was that i was unable to calculate empirical formula!!
