For PSIR Optional preparation, how do you usually decide whether a coaching platform is actually worth joining?

I’ve been hearing about Sumit Sir for PSIR Optional and wanted to understand from people who have already prepared this optional—what actually makes a coaching platform worth joining?

My main concerns are affordable fees, teaching quality, answer writing support, mentorship, and consistency throughout the course.

For those who have studied under Sumit Sir or followed his guidance, was it genuinely helpful for conceptual clarity and answer writing, or was self-study with standard sources more effective?
