Advice - loosing interest

There is no straight jacket formula developing interests. Evaluate subjects you like - spend 3 hours on it and 2 hours on a subject that's not so engaging.
Everyday do 4 subjects. So total 10 hours.

Take short breaks, good sleep, dedication and discipline.

For me, Studying was a motivation itself. You will have to find your motivation if that's missing.

And make your own notes, generally a pen,paper and some notes in your handwriting increases focus and builds interest.

A proper index, use of colour pens helps alot more at crucial stages in the preparation journey.

True...Thnk u so much!!!
