Dear learner,

yes you can ,there fore you have many pgd ,msc,pg courses after bsc geology ,if you do masters in geology you have a scope to become a environmental scientist

as pg diploma in forensic and criminology takes 1 year duration you can't become expert in forensic ,if you are from bsc forensic background and willing to do pgd in forensic you'll become ,but there are some relevant jobs regarding pgd forensic with bsc geology

you can become forensic anthropologist ,forensic handwriting expert, forensic ballistic expert etc.

eligibility for pgd in forensic sciences is bachelor degree in bsc /btech/pharmacy/medicine obtained from recognized university board .

All the best .
