Hi Vinay, to answer your question specifically will need some more detail like what is your current qualifications.. What is your age etc... And to answer can you give IFS exam with medical or biotechnology.... First you have to understand these two are quite different streams... The eligibility for giving IFS is minimum 21 yrs old, should have minimum qualifications of Bachelor's degree with at least one of the subjects namely Animal husbandary & Veterinary science, botany, chemistry, geology, mathematics, physics, statistics, and zoology or a Bachelor's degree in Agriculture, Forestry or in Engineering of any of Universities or possess equivalent qualifications...

For medical its PCB subjects in 11 & 12.....and in medical there are various courses like MBBS, BDS, BAMS, BHMS,  etc..... All these is a bachelor degree... After getting the degree you will be eligible to give UPSC exam preliminary.. Then IFS mains and interview......

Hopefully it helps
Best of luck
