Changes in cs final modules

Dear CCI friends,

I am going to appear in CS final examinaion in this June for 2nd & 4th group.

I prefer to read from modules only. I have registered for CS final in May, 2010 and got the modules.

But since then there may be changes in some of the topics in the module.

Please tell me is there any changes in the modules since then?

Should I continue buy new modules?
