I would be using it for the basics: Research/Internet, writing papers, studying, social media etc.
Regardless of what you might want, your apparent needs dictate something other than a MacBook Pro.
Being a bit of luck for you as the current roster of MBPs are regrettable in many respects, and you can save some money in the bargain.
If you are dead set on a MBP, consider the 2015 model. The 15 inch model is still sold new by Apple, or at times can be found refurbished by them (being a good choice). It comes sans the gimmicky touch bar most have discovered to be rarely used, an annoyance or worse. It does come with an excellent keyboard. As well plenty of power even in the base configuration. However if you will be carting this thing all over campus, 15 inches might become a bit much.
Something new (or, again, refurbished) which might suite you well is a MacBook. For relatively light tasks it should have all the power you need, and in a responsive fashion. It can be and need not prove all that expensive to purchase. Not to mention being compact, light and portable. Negatives could lie in the single port and keyboard.
With any of these modern Mac keyboards be advised and try it in person first. Reports vary but it is usually a love it or hate it proposition. Also know that such a keyboard may experience maladies sooner than later, requiring servicing (that you definitely do
not want to pay for).
Another possible and likely choice would be a MacBook Air. It is Apple's still iconic but now ignored stepchild and entry model. But that is to their discredit for otherwise in many respects an excellent choice.
The Air is not as compact as a MacBook or even the newer 13 inch MBPs, but still fairly light. Unlike the MacBook it has a fair number of useful ports, and is decidedly more powerful. If you wish something near the power of a MBP but more svelte, it could be a good choice. Not to mention less expensive.
Negatives of the Air rest principally with its regrettable screen. It is serviceable, okay, but no contest to a retina or even a classic MBP. Then there is the further insult of the wide silver bezel Apple never saw fit to change, as in something more practical and black as with most every other laptop they've ever made. Some manage to overlook this slight, though.
Anyway, you might reconsider just how much you need a MBP, or if so which one. Apple may make amends for past transgressions in their laptop offerings come 2018, but I wouldn't hold your breath. The new models generally have the best specs, if that is all you care about. However in a few more years they too will be out of warranty and Apple will have long since lost interest. That new today will likely in time not weather well in comparison to what may come in future, nor, certainly, to more solid and overall better Apple creations of the past.
