The CBSE forum here is total shit, so can you guys be kind enough to help me out? We've had our physics paper and I couldn't complete it on time, and now I'm scared as hell for Bio and Chem. I took CBSE in 11th and 12th just to concentrate on my med entrance, so I naturally didn't practice any papers and stuff. Could you guys give me some sort of tips? I know CBSE is different, but still, any kind of help would be appreciated.
