Hello there

Yes, ofcourse you can crack this examination by self study. For that you should take care of some things which I am describing here.

• Firstly try to develop inner confidence that you can crack this examination by your own self study because that is very much important.
• Now firstly know the syllabus and try to stick on on one book firstly and after completing that move on to the another standard one.
• Always try to make good friends and if possible make the friends who are also preparing for this examination and try to compete with them by making healthy competition.
• If it is possible then try to join some test series and try to give as much as mock test you can online or offline.
• Now lastly be honest to yourself and be self disciplined and also try to solve as much as questions you can.

I hope it helps you!

Good luck!
