how to develop interest while memorising points because when i learn half of chapter i feel very exhausted 
 

Dear Student ,

Try memorising the important points in a sequence or manner of your own.
Try creating a story of the points and join them while writing your answer.
You can also memorise the important points for your exam by writing them in your own words , Simple and Unique.

Also, don't try to finish the whole chapter in one breathe. Try completing it by taking breaks.
Refresh your mind before reading.
Stay Clam and Positive.


All the Best.
Regards!
