Football Tickets for 8/31

First of all I’m lowkey lost on the ticket situation like do we always get free student section tickets or just a certain amount per semester? If there aren’t free tix available can I still pay for one to be in the student section? Also are there any student tix left at all for this weekend because I don’t think there are unless I’m doing something wrong. Andddd lastly if I end up having to buy my own ticket is there a way to get to the student section once I’m in orrr what does that look like? THANKS GUYS
