Hello,

every sector will be demanding as they contribute to the Economy of country. For now, as business is shutdown, government is providing aid  by taking loan from international and national banks.

if you have biology as optional subject then you can go for Medical stream which is highly demanding now and become more demanding in coming times. You can also for medical care streams through BSc course, diploma course.

other than medical, you can opt for Biotechnological engineering, pharmaceutical, chemical engineering. This will be leading streams now.

Hope it helps!
