In big problem...........?

dude as per my own experience you should'nt do anything new at this crucial tym.. this is the tym for revising whatever you did before.. so do not start anything new just revise.. doing do any new chapter in cost n a/cs as you told you've left will take your more time.. on the other side if you u invest your this time in revision you can revise one whole subject. so revise revise revise as many times as you can

I think if you have time than you have to revise SM, Major chapters of Income Tax and Company law.......But dont try anything new.......................

if you fail in a single paper, you will loose the whole group.Thus think with the cool mind and come out with any idea so that you have atleast chance of passing in all subjects rather than concentrating on only one or two subjects.
