Last minute advice

hi all, I've prepared well for all my group 2 exams (IPCC) my only problem is with information technology. I'm quite good with computers and am also quite tech savvy but I just can't seem to remember the institutes language given in the study material. I can give answers in points in my own words (quite confidently) . I keep reading everywhere that on GRP 2 the make or break subject is it&sm as most fail in it. can I answer in my own words and is it necessary to write long paragraphs or is writing to the point sufficient? can anyone with prior experience/ experts give me some last minute advice. inputs appreciated.
