Should I take drop??????

Should I take a drop for JEE 2027?

I got around 40 percentile in JEE 2026. In Class 11 and 12, I barely studied and wasted most of my time on YouTube, WhatsApp, and social media. I was not consistent at all and sometimes studied only 1–2 hours in an entire month.

I scored about 70% in Class 12 boards.

The thing is, I don't think my 40 percentile reflects my actual potential because I never seriously prepared for JEE. Now I am considering taking a drop year for JEE 2027 and studying full-time.

My questions:

1. Is it realistic to go from 40 percentile to 98–99 percentile in one drop year?

2. Has anyone here made a similar jump after starting from almost zero?

3. What were the biggest challenges during your drop year?

4. Would you recommend taking a drop in my situation, or should I move on to another path?

Please give honest advice, even if it's harsh. I want realistic opinions.
