We can expect the notification for RBI assistant by the end of December. As RBI Grade B exams are done, we can hope RBI will come up with assistant notification. I suggest you to start preparing well for the examination, so you can clear it in one go. Dedicate at least 5-6 hours daily for your preparation. Practice mocks as much as you can. Revise the concepts. You can definitely clear the exam. If any doubts, pls feel free to ask !
Wish You Good Luck !
Thank You !!
