Purchased cat mock test series, what is the order of taking first(Dashcat or headstart mock)?

I think some of the headstarts are prev year dashcats so , you can start with some random headstarts and then go for dashcats

If you are looking for mocks closest to actual CAT, start with DashCAT 1, DashCAT 2 & DashCAT 3. Headstart mocks might be slightly easier compared to DashCATs.

first headstart and then dashcat
