the suggestions all tied so im going with the only non silly response
(although its worth noting that harbs suggestion was only silly because he was metagaming)
Force damage.
It's a weak spell.
"i want to turn my magic into a bolt of pure force" you say "excellent choice" says the teacher "a knowledge of force can lead to the ability to levitate objects and manipulate the world around you"
"now when you turn your magic into force make sure you do it after it leaves your hands if you create the force in your hands it will explode outwards in all directions and you dont want that. one day you will be able to create a counter force that pushes in on the outer force to cancel it out for now i will place a spell that will prevent you from ripping your hands apart." he conjures a target taking up an entire wall of the room. "now push your magic out and just after you release it turn it into force this is the basis of most spells".
It takes you 3 days but eventually you do it you feel the magic leave your hands and feel it turn to force, followed a moment later by a massive hole being ripped in the wall.
"holy shit" you say "thats a lot of power"
The man laughs "oh that gets almost everybody i turned the wall into a weak paper there wasn't that much force in your spell anyway you are now ready" he conjures a door behind him and motions you through. you walk into an expansive room about 5 by 5 meters in length with yet another man. "welcome" he says "you are now ready to begin your training proper i shall give your your equipment an explanation of how it works after that your on your own". "this is your first item your robes" he says as he hands you a set of robes which you put on you fell like a proper wizard now.
"this next item is by far your most important" he hands you a simple stone tablet. "this tablet contains a map of the grounds, a list of classes you can attend and any other information your could possibly need both on magic or the academy" he launches into an explanation of how it works it seems fairly intuitive its like a touchscreen tablet only stone and can also be controlled by voice. it also allows you to bring up a large range of information and communicate with your professors and other students it can do pretty much anything you wont need that laptop it gets an Internet connection.
"the rest of the things you might need such as alchemical equipment and basic items on which to practice enchantment can be found in your room you are now ready to begin"
You walk out the exit door and find yourself at the front gate you check your slab and find the following options suitable for your skill levels.
Professor Bill Zavatsky is about to teach a class on creation of fire
Professor Mike Desiderio could teach you some further manipulation of force
Alternatively you could go check out your room or do some socialization or maybe just do some practice on your own.
