Hello student it can't be predicted if the mock test are easier or harder than the actual examination I request you to please help with the entrance examination you're concerned about so that I can check and provide you the exact information. Mock test are for practice so that you can get a overview of actual examination and work on your weak and strong areas. Solving mock test is on thing but analysing is very important so analyse each and every mock test.

Feel free to comment if you have any doubt

Good luck
