Hello,
I suggest that you refer to the BS in Biological Science curriculum here to get a better idea about the electives BS students can take.
At IITM, you have different categories of electives:
- Professional electives: Every department has its own set of professional electives, from which the student can choose according to their interests and career goals.
- Humanities electives: All undergraduate students at IITM are required to do 27 humanities electives, this number might be different for your course so check the curriculum on your department website. The set of humanities electives offered to all students is the same, irrespective of their department.
- Science electives: Courses from the Physics, Chemistry, and Mathematics departments are considered science electives. They are open to students from all departments.
- IDDD electives: Every IDDD stream has its electives, which you can check in the curriculum. So all students in a particular IDDD stream have the choice to choose their IDDD electives from the same set of courses irrespective of their Bachelor’s stream.
Students also have unallocated credits, which you can use to take electives from any department. You read about how minors work at IITM here.
We can’t give you advice on admission to graduate programs. Still, these programs are generally very competitive so while a minor will aid your application, you should refer to the programs you are interested in to understand the eligibility criteria better.
Hope that helps!
