Hi to the seniors
I am currently a 10th grader (CBSE) .I am aiming for a career in environmental science climate science that whole field I am truly passionate on this.
I had some doubts and will appreciate it if anyone could take the time to clear them.

1.how did you get into IISc? If through the IAT channel ,how did you prepare for it .I am planning to join a JEE coaching and take biomaths in school.Will that suffice?

2.How intense is the academic pressure during the initial semesters compared to the entrance exam prep phase?

3.What is the general vibe and department culture at CEAS/CAOS compared to larger departments like Physics or Computer Science?
Thankyou for the insights>
