is it a good idea to finish bio + chem first?

i’m planning to finish bio + chem within the next three months

for bio i’ll do 5 pages of ncert daily
for chem i’ll watch 1.5-2 lectures daily and study ncert and solve mcqs

i’ll give tests and revise on weekends and by nov 30 i’ll complete both the subjects.

then i’ll do physics in 4 months and then one month revision only. i know doing all three subjects is ideal but i’m not able to handle three subjects daily since i have school too.

my goal is to just get my state gmc which closed at 26000 rank in round 1 so is my plan good enough to get a 20k rank?
