any tips on my state exam?

So I 19M Just got a job with a life insurance agency as a life insurance agent now I have no idea about anything about any of this stuff until I get this job and so I’m going through my 20 hours of prelicensing course and I only have 3 days from when I get my 20 hours before I have to take my exam and It’s just so much information thrown at me all at once that I can’t process at all.

Does anyone have any tips or experiences as how they got through their exam because I just feel so lost and every time I take a test to practice I 2nd guess every decision I make and even though it’s the right answer I change it last 2nd and I get it wrong

There’s a lot riding on this final exam for me as it’s life changing and everything is riding on it I know saying that definitely doesn’t help the stress But I have a wife and 2 kids and we’re having a lot of financial problems at the moment So in my head it really feels like everything is riding on it

I just need something to try to make this whole exam a little bit easier even if it’s it’s super simple anything helps
