Hello student I request you to please help me with the entrance examination you're talking about, if your start solving numerical problems as a revision and polishing your concepts then yes it's very helpful it'll help you inn the examination but if you start solving numerical problems from the beginning before 10 days then it won't help you as you need lot of practice. Solve as much mocks as you can and after solving them analysis is very important so that you can work on your mistakes and correct them.

Feel free to comment if you have any doubt

Good luck
