I agree that the marginal benefit of practice tests diminishes - I was more perplexed at the marks you were getting when you claimed to fully understand the material.
Using your method, the base number of practice tests would be 2 - 1 as a diagnostic, which you said you would spend a week to review thoroughly, then a 2nd test as a way to assess your progress over the 1st test. In that case, wouldn’t it stand to reason your 2nd test should reflect higher scores then 70% and 68%?
