Hello aspirant,

No, you cannot apply for IISC bangalore as a PCB Subject. IISC requires Math as a subject in intermediate curriculum so if u are a PCMB student then you can apply but not only with PCB .

Furthermore, although there is no specific subject offered in the Bachelor of Science (Research) program, You can still take biology as the major subject in the courses.

Further, to know more about the IISC Bangalore Courses, and other relevant information, you can follow the below mentioned link to know more : https://www.careers360.com/university/indian-institute-of-science-bangalore/courses

i hope that this will help.
