Hello aspirant,

If you have a BSc in biological science, you can pursue an integrated PhD at IISC. For B.Sc. students who wish to pursue research and a PhD shortly after completing their bachelor's degree, IISC offers integrated PhD programmes. This style is highly competitive and perfect. Candidates who meet the requirements of the admissions process and have a valid entrance exam score are summoned for in-person interviews.

Thank you

Hope this information helps you.
