Hi Umesh,
It depends on in which you are more interested.
I would suggest you go for B.Sc in agriculture because it has more scope than B.Sc in forestry. You can get jobs after B.Sc in agriculture in the following fields:
1. Agro-processing Industry
2. Input Sector
3. Government Job
4. Banking Sector
5. NGO working with rural background
Still, I would suggest you find your area of interest if you are interested in forestry, do it. Do what you are interested in.

Well, with the above-mentioned marks, you cannot get a government college because in any government college there has a criteria of 60% at least in your board exam.
You can go for a private college.
