sir

i want upgrade my branch in iit. so pl. tell me which branch is better in series Biotechnology, Civil, Chemical, Electrical, Electronics, Mech. & Computers (pl. arrange in desending order)

Ideally it depends purely on your interest.
But still if i arrange according to current marking senario
Computers> Mechanical>Electronics>Electrical> Civil > Chemical> Biotechnology

Also this order can be influenced by the which college ur in and also place. Which city the college is located also affects placements

Also think about the time. This is a era of softwars and APPS so softwarre industry is at BOOM but tommw its possible that govt introduces new every states starts building metro in their areas there will be grt demand of Civil Engineers. So decide wisely

Think of all this wen u take your decision.

At last I would say if you have interts in any subject you will find yr way out
