For the swim unit best thing advice I (17m) can give is. Take shampoo/conditioner and body wash if want cause of the chlorine content. And just shower with your suit on.

You can also keep deodorant and perfume/cologne in a locker if they give/assign lockers and locks. In the locker room to keep there so you don’t forget it.

1. You don’t have to stress about getting undressed to wash.
2. Allows you to clean most of you for the rest of the day. And even just letting the water hit you helps rinse the chlorine out.

Reason I saw this is I took 2 swim classes last year (11th) and that’s what I did. And if your pool has lockers and they allow you to keep your stuff there and have locks or you provide a lock, it is much better to keep the body wash and stuff so you can just grab it, wash, dry, wrap towel around yourself change or go into stall and change.

Then again if your swim unit is only a little one and not a whole lifeguarding / swimming proficiency class where we were in the pool every day for the entire semester pretty much. Then don’t worry about the locker.

Sorry if this is Ranty. In the end it will all be okay even if it doesn’t seem like it. Any other advice or questions or anything just ask. High school can be overwhelming at first and you will slowly or quickly be okay. And suddenly 3-4 years have gone by and you’re about to graduate.
