Dear,

Everything depends on your skills, knowledge and experience thats what I think. Although there are limited courses available in Bsc. having 100% placements like:

1. Computer sci

2. Information technology.

3. Microbiology

4. Biotechnology

According to my point of view these have great placements and highly paid than rest.

Although we cannot say what happens in near future. Everyone is getting specialized in different areas and starting new business.

Just make sure you are well versed in one specific area so you can even start your own business. 

Hope this helps.

All the best!
