I'm in the same situation as you, being a student studing game design. I think this would be a great jam for you to begin with (it's also going to be my first full jam), mostly down to the fact the jam is 30 days long giving you plenty of time to make a simple game, I would recommend using a game engine you are familiar with and only aim to try 1-2 new things. The combination of creating a simple game, using familiar tools and not attempting too much outside your comfort zone should give you a decent chance of completing your project. And even if you don't complete it you'll still learn alot :D
