How many hours should you sleep while preparing for the NEET?

I am preparing for NEET i sleep 7 hours and take one 15 minutes power nap during study time

I used to 9 hours till july but i have added 2 hours more since August. That is i study 11 hours. I have not joined any coaching i study in library. All these 11 hours are of self study

To be honest

In these 11 hours

For 7 hours i study with full Focus i don’t even realize when 7 hours passed

Then i take my power nap

3 hours are 75% effective

My study speed is decresed by 25%

1 hour is 50% effective

But Atleast i study

I does hardwork on my smartwork

And trust me results are marvelous

Studying at library is somewhat better. No distractions at all.

You have nothing to do rather than just studying

I can’t even see whats going on my front right left due to compartment division

Even when i am completely saturated i can’t do anything rather than just studying

I am so thankful that i don’t have a smartphone

Whenever i sleep. 80% of my dreams are like this

I am doing great. I want to maintain this habit till 6th may.

I enter in my house at 9:00 pm and sleep after having dinner me and my brother live in the same house but i have not seen him from 24th August

I just want to see my MAMC hostel roommate face now.

Blessings are always with me.
