My First tournament any advice?

Don’t listen to these bozos. Put in the work and hours and you can be a world master. Everybody can if the put in the work.

Beat 2 people in 5 rounds. It was an under 1400 I'm unrated in person but guessed about 1100-1200 so I was high up there
Honestly with all due respect, u are trash and won't be winning anything before u get good ... it's just a waste of money for u right now.Instead u should invest that money into getting good
Well I beat 2 people in 5 rounds
Well,if u had invested that time,money and effort in learning more, pretty sure u could have scored 4/5 if not 5/5
It was my first tourament I have autism and get a panic attack easily. Also first player I had played an opening I've only seen 2 times in over a 1000 chess games on lichess and was rated somewhere from 1350-1390. In fact that boy won the whole under 1400 part. I've only been playing chess for like 4 months so give me a break

List the ratings of all 5 opponents. People on here can give u a pretty close estimate of what ur 1st rating is. U scored 40% vs an unknown average rating, that average rating is important. I think 40% is kind of good for ur 1st event, even in an u1400 section.
Today will be my first ever chess tournament. It's a swiss tournament does anyone have any advice for playing in an swiss tournament or just general tournaments?
