Could I handle this plan on the coming months or should I drop any course?

My plan is as follows :-

(1) Taking SAT2s this June ( I already finished the study of the courses and currently re-practising all the real tests).

(2) Retaking the SAT this may (I’ve been into this for 2 years but I’m definitely not satisfied with my 1740 subscore). I’ve practised in all the books and in the bookstores the only book left to me for practising is the Barron’s (I did 2 tests until now and I’ve 1820 however in real practise tests I’ve reached 1970 :smiley: ).

(3) Taking the APs (Just will start.) … (Environmental - Art History - BC Calculus)

My study potential is 4-6 hrs.
