Hi,
With your architecture degree you can design structure keeping in mind of every environment aspect.
You can design houses in rural or urban areas with set up if solar panels on top for the electricity issue. This is the example through which I want to explain you that having degree especially in environmental science is not necessary. You can help or save the environment with your passion and knowledge.
All the best!

You should opt for B.Sc (Hons). It gives you specialisation in a particular subject and better job opportunities.

Since you were having PCB, then medical stream which includes MBBS, B.Pharm, BHMS, BAMS, BVSc, B.Sc nursing etc or B.Sc in agriculture, BA psychology etc. might be of interest to you. B.Sc in science, biotechnology and bio-informatics are also not bad choices.

St. Xavier's, RUIA and Jhunjhunwala are some good colleges for M.Sc in mathematics.
