Hi aspirant

thanks for asking your query as you have done your msc from industrial biotech therefore you should opt for gateBt because you have studied biotech in msc which would help you to crach gateBt easily where as in gate life science may have certain syllabus of biology.

Its a thing that totally depends upon your self. No body could ever guide you in any way. Yiur soul interest should decide which streams to choose and move ahead. May be some will say do one or other but it might be that you can do better otherways so its better to lead a decision by yourself seeing scope interest and everything.
