Alternative Solutions are Gold and Mistake Analysis needs features

GMAT Club Quant tests have been incredibly useful and helping me to increase my timing on and understanding of 700-level questions. The major drawback is the mistake analysis section, which doesn't allow the user to compare performance on the same question formats across many tests that had been taken. For instance, it would be great to see what is the ratio/level of right/wrong answers in combinatorics in my last 5 Quant tests. In some way, Manhattan GMAT has a similar analytical tool on its website when you take multiple tests. Basically, it would be great to track my progress in specific sections of the Quant that I feel need improvement.
