Query related to Cracku

So Iam going to be appearing for CAT 2025, and I had subscribed for cracku CAT course. Now, my doubt is how to go about with the stuff? Like should I just do the live classes or is it live classes + study room? I joined in between one ongoing live classes schedule I think, they have already completed a lot of classes in it. Do they start a new batch soon? Or should I just follow the current set of live classes? Could anyone who has used cracku last year or is currently using it solve this doubt for me? Thank you! :)
