Magically speaking? Not a lot beyond cantrips, unlike some people they can't get more spell slots by having sex.
(Though you could easily be misled on that by how much sex is had on campus. These are co-ed youths living under the shadow of a mortality rate comparable to fighting in a war.)
At this time of day most of the student body are at least supposed to be attending their lectures and tutorials in the various halls of the Acadamae. Those outside are those between lessons or skipping them, along with all the apprentices doing the drudge work that takes them outside. Unseen Servants are ordered around, Prestidigitation cleans the latest messes, a Floating Disk carries heaps of spellcasting supplies behind the student delivering them, and clusters of wizards-in-training amuse themselves on the steps and benches with games of chance or skill, contests of lore or Ghost Sound impressions, or in one case a duel-by-proxy between familiars.
One student, a lanky human who looks like he's still in his teens, tries to match her pace by running alongside her for a few dozen paces, flashing her his best attempt at a charming smile and perhaps not coincidentally putting himself in a position to glimpse whether shoes aren't the only item she isn't wearing. Most are not so daring.
(The daring and unwise make up a noticeable fraction of the 20% who fail to survive their first three years.)
