I would suggest that just giving mock tests is not enough. After attempting the mock test, you should analyse the mock test as well.

After attempting a mock test of one hour, you should analyse it for at least two hours. The purpose of mock tests is to identify your weaknesses and that can be done by proper analysis. Analysis should be done for each question and each mock test. In this way, if you attempt a mock test then it would be perfectly fine.
