Commercial furniture makers use dowel and glue or KD (knock-down, cam and dowel) fasteners for flat-pack furniture. Smaller workshops use biscuit joints (look-up Lamello, biscuit jointer, etc) or sometimes screw items together using a glued joint and carcass screws.
If you can get access to one I'd suggest using a biscuit jointer.
dowels cams or buiscuts or you could machine dovetaills with a router and jig
the cheapest option is [assuming its half inch-12mm]mdf is
6x1.5"screws a 3 or 3.2mm drill avoid the 25mm each end
butt joint the components screws every 50 to 75mm pilot the full depth of the screw through both components
use the pozi srewdriver bit for your countersink glue and screw together hand tighten the last 2 turns
if the edge does delaminate slightly push glue into the crack ,unscrew the screw a few turns block and clamp then tighten screw
But if, for example, the teacher has spent three weeks demonstrating and instructing use of the biscuit jointer, he will be disappointed with screwed butt joints.

Just curious - I was taught mortise and tenon joints, but then MDF wasn't invented until later....... Do they teach the use of biscuit jointers these days? And why should you need to do what the teacher says? After all industry doesn't work the way teacher says.....
