I appeared for 40+ Mocks this year and I made sure that I have a tracking sheet where I can analyze and improve.
Having a tracking sheet is a must. CAT mock is just 40% Task. It's analysis is 60% important. It's an analysis that will make you succeed.
You can check out the mock tracking sheet that I used.
PS: It will not have my mock scores. It's the template that you can use.
