Can manage 2nd group(ca final old) now to study?

I have completed 1st group all 4 subjects 50%-60%. I have given attempts before too.
Now i want to give a try to group 2 also.(have studied roughly for may 19)
Assuming I have studied 20-30% of portion after may 19 again. (except DT).. And considering mcq in 3 subjects i grp 2

How can i allot time to grp 2 to make it(or best try)??
