I’d work through those first – topic tests, EOC and 3 mocks are a good healthy amount and a lot more than what they used to hand out to candidates. You might find it’s enough, and if it isn’t there are always top-up packages from providers you can get.
For L1 we also have two free practice tests you can use:

Our partner providers also have full versions of their products made free through our links below:

Together with your CFAI material, that’s a lot of practice!
