Hi !!

It will depend upon certain factors -- like if your exams is near then no need to pick up new books/topics as it will mess up and will make you low in confidence..Don't start new topics , just revise done topics..

and 2nd condition is when your exams are not near ,then you can start a book and learn new topics and do new questions ..

I hope it will help you to figure out what you should do .. Thank you
