First Fight June 24th need advice!

[TyBuff]

I have signed up for my first Fight Night June 24th at my boxing gym. I am currently training with a guy about twice a week and visit the boxing gym about 5 times a week. I would like to know what I should expect and what I need to be doing up to that day. I do cardio. I spar. I go to the gym. My diet is clean.

Its only 4 rounds

Is this amatuer, pro, or just sparring?
