deciding between how to allocate time for different subjects for exam.
different choices.

if study for coming 10% test, face the possiblity of not having enough time for three later subjects.

but if forsake 10% and start studying for 3 later subjects, the 10% subject will get almost zero which i feel is a big loss.

feel a little stress which should not have happen. got a little absorb into the issue forgetting the body physiology is being connected to issue.
