Title: Crackd.SAT — how accurate is it compared with the real SAT?

I already bought Crackd.SAT and now I’m wondering if I made the right choice 😭
For anyone who has used it, how similar did you find the difficulty and question style compared to the actual Digital SAT?
Also, is Crackd.SAT actually College Board approved or officially partnered with College Board? I’ve seen people say different things about it and I’m confused 💀
If you’ve used Crackd.SAT and then taken the actual SAT, how did it compare? Is it good practice or should I mainly stick to Bluebook/Khan Academy?
