Bio technology is a research department study but EEE is electrical and electronics engineering is engg work.More over EEE is easy comparison to bio technology .
You direct joint B.E EEE dept 80 % easy and bio technology 60 easy.
Another choice you to join the diploma EEE course and study B.E EEE  is more useful full and full easy.

EEE is tough As a electrical and electronics engineer myself I refute all things they say as it's is difficult and hard.  There are so many opportunities in EEE. You can get the advantage of both Electrical and Electronics . So EEE is a core branch.

Hello aspirant, in my opinion, biotechnology is bit easier than EEE engineering. But I also think that EEE has better scope. So I think you should choose your option not according to which is easier but on the basic of your interest.

Choose your option in which you have most interes.

Hope this helps. Regards
