aab se har roz ek test solve karo
that will help u
i too have my BITS on 20 and i am relying on solving test everyday now
tumhara jo slot hai us time pe test solve karo
it will be very helpful
time management me bhi test will be useful
so my only suggestion is that even if u dont have much time to revise concepts, just go about solving test
as much as u can................................din main do karni pade to wo bhi karo but surely solve some papers
