HI Rachita , i have flunked in Group2 twice and i got fairly good marks in IT .SM in both the attempts. May 2009 -55 , Nov-09 -56 . I think you can study SM if u can make ur own notes ( I made my own Softcopy notes from Inst PDF books _ Study MAt Copy imp lines and sentences from the Mat and paste it in a separate word). Take note of only imp points and take a printout of the same. it is more than sufficient. while copying read each and every sentence very thoroughly.
Regarding Infotech u should do thorough study of Mat and understand various concepts, Working of various componenets of comp, DB, EDI, E-payment systems, ES, AI, Networking Hierarchy, topology etc(Pl do a good research of some imp concepts using internet so that ur conceptual understanding is clear and if ur clear that ways, just one or two revisions before exam is sufficient to get 60+.
This is my idea. Hope u may find it useful. all the best for the exams.
