it depends on the seminary but what goes on at my seminary , is you will show up probably on a friday afternoon, you will move into your room for the weekend, then you go to Evening prayer with the seminary. After that you will have dinner, then you will probably have some type of talk after that, after all that is over the come and seers get together and do night prayer which many times is optional. (to do it in communion) Then you go to bed
Saturday you wake up for morning prayer, and then possible go to mass right after (it depends on your seminary) then the rest of the day I can’t really remember will consist of talks reflection time prayer, and so on and so forth. Evening prayer later in the evening more talks and Night prayer and Bed.
Sunday morning prayer again, then you go to mass with maybe a couple other things, then after Mass you have lunch with your parents more then likely if they choose to come then you are home free for the weekend.
Its a great exoerince and will for sure help you discern what to do

Arrive 4:30
5:15 welcome talk

This is a very rough schedule from my memory, Its been two years since I have attended a come and see, and we haven’t begun to talk about this years come and see.
Weekends are usually very open for seminarians if they don’t have anything planned
For example
this was my weekend,
Friday
7:00 breakfast
7:30 Morning Prayer
8:00 Schola
9:30 Formation Class
11:15 Mass
12:00 Lunch
1:00 common work (I did this but it only happens once every 5 weeks)
or
2:30 health and weakness (I do this on all weeks but on common work weeks)
5:45 Open Forum (first one we have don’t know about how often it happens
6:15 Evening Prayer
6:30 Dinner
Saturday
8:00 Morning prayer and Mass in spanish
9:00 Football practice (optional to play on the team but if you are on you have to play)
12:00 lunch
6:15 Evening Prayer
6:30 Dinner
Sunday
8:30 Morning prayer
10:00 Schola
11:00 Mass
12:00 Lunch
6:15 Evening Prayer
6:30 Dinner.
so I have no idea what you will be doing because closed weekends as we call it here are very free for seminarians on purpose they want us to study.
