as an hobbyist on a shoestring budget, but with the head in the sky, based on my own experience:
8GB Ram is ok, 16GB is nice
most important, aside 'skills': …
<voice of Steve Balmer> ext HDD, ext HDD, ext HDD, ext HDD!!!

I'm handling here 4k material on a MacMini, which doesn't even have a dedicated GPU. In Multicam.
Distribute your materials on several hard drives, make a plan first, before editing, what & where, you get instantly messy and lost without a plan.
What mentioned before: back ups! I'm not shy using a 99€ Raid0 (=two 2.5" drives + Disk Utility's feature, to create 'software raids' ) - Raid0 are NoGo for pros, 'cause it doubles the chance to 'crash' - no prob for me, having my backups - inconvenient to reload everything - but I'm no News Room 😝
For professional 'look' care for the other stuff :
tripod with 'fluid head', lights, more lights, ND filters set, ext. microphone(s) at last a shotgun and a lav, ext audio recorder (I'm abusing my ol' iPhone4 and a tiny box called iRig, which offer XLR connector), did I mention lights? , a good bag and a waterproof, lockable aluminium box, soft boxes for light, maybe a shoulder rig (starting at 80€), 200sq ft of some green cloth for green screening (if your school doesn't offer a 'studio') FCPX does marvel with even really bad lighted green screens, those handy foldable 'brighteners'/reflectors, to bounce light ('Rembrandt lightning') … finally tons of odds and ends, starting with gaffer tape, ending with SDcards ...
And DO things, try things, play with your stuff, make experiments just for the trash bin!
Enjoy your film school (I'm envy… 😉 )
