Should I give a mock daily ??

Its more crucial to analyze the mocks on the same day to know where the maximum time went, which we couldn't solve, what are silly misses and concept gaps, if you can then go ahead, but i would recommend you to keep yourself free for 1 or 2 days before CAT

No. Giving a mock daily isn't the best strategy. 2–3 mocks per week are enough. Baaki days mock analysis, weak topics aur sectional practice ko do. Remember, analysis matters more than the number of mocks!
