Help a fellow NEETard out

So I started prep very recently after dropping out of a completely different degree and I’m attempting NEET 2026 to see how it goes. My goal is to just qualify via biology only cuz I am too tired to do physics and chem for this attempt. I’ve done 23/32 chapters but have forgotten a lot like scientists and examples. When I’m doing tests my score is 50/50. Could qualify comfortably if the paper comes from the chapters I did or miss the qualifying marks by 10-15 marks.

What do I do to secure atleast 150 in biology.
