According to me B.Tech in CSE is better than B.Sc in CS. You should go for the college which has collaboration with MNCs to set up live project labs for students so that they could learn working on projects at corporate level.

Both are equally good courses, you have to choose according to your interest only. After doing both courses, you have good job options. You may get both government and private jobs. The only difference is that after doing BPT, you will be designated as a doctor and you can do your own practice and after nursing, you will be known as a nursing sister only but both have good career scope in future.

Yes, after completing your honors degree course you can go for IPS.

Dear,
Kindly specify a short introduction about yourself, your favourite subjects and your career goal then I would recommend you a few options.
All the best!

Dear,
After B.Sc in biology, life science or zoology (Hons.), you need to choose specialisation in Masters for further growth.
Microbiology
Stem cell research
Horticulture
Genetic Science
Nano Science
Wildlife Science
Environment Science
Clinical psychology
Choose the right way for your further education and growth.
All the best!

You can go for M.Pharma and become a drug inspector after it.

The question itself is illogical. Why would one again spend 3-years to pursue an undergraduate program after completing graduation? B.Sc mathematics doesn't have a great career except in the field of teaching so definitely it depends on what you want to do.
