Help me not to overthink

I'm sitting on Exam P this May and currently enrolled to The Actuarial Nexus and XP Actuarial (Udemy). I've gone through all 627 sample questions of SOA and have gone through all questions provided in TAN. I am able to answer all questions (not memorizing the answers).

Is this enough to pass Exam P or is there anything else to do? How similar the sample questions to the actual exam?
