B.Sc

hii,
bsc + msc (chemistry honours) is a good idea but when you paased with biology then you should do honours in biology because after completed your master you can get a chance to be a good faculty on coaching institution. with high package of sallery

yes he can as he has secured a gd mark

none of these studies r easy to study.to get success its compulsory to work hard in any field.Though u feels u can't get good results.
in dat case its better to do B.sc fr u.& yes there ll be various path fr u aft completed b.sc.u can prepair urself & apply various govt
jobs aft graduation.Good Luck !!

You should have biology in your intermediate and should secure a percentage of 50%. SC or ST candidates may get a relaxation of 5% in the eligibility criteria.

MCA.but now a days only taking post graduation in computer and IT alone cant do. Choose any particular field of your interest any be expert in that. For instance if you have intrest in programming than be expert of that apart from doing Masters.

That solely depends on your interest! Bsc will need a side of research while btech will need more interest in reinventing things and make them better and economically viable!

bscit will be helpful rest depend on ur interest
