Best wishes + Paper Discussion Mains 2024

In a dilemma between IFoS and CAT 2024. Both on the same day.

Would appreciate clarity on:

1. How is the IFoS as a service?

3. Any inputs on CAT vs IFoS?

3. Pros and cons of going for CAT after a 2 year break. I'm an engineer (GEM) from a tier 1 college.

Thanks in advance.
