Help me buy a graphic tablet to join a art class!

I am an architecture student seeking to afford à drawing tablet for a digital drasing class as my part-time job salary only covers my living expenses

Hi, I'm an architecture student, hopefully my studies re going really well, I have great results. I also have a passion for drawing and art since little, witch motivated me into choosing architecture where i can use my creativity in a more practical setting . But I recently had the opportunity to participate in a free advanced graphic design class. More important notions will be studied there, and it's a really great opportunity for me! To widen my knowledge in drawing as a whole! Since my part-time job salary only covers my rent (I live with a roommate), and grocery shopping, I can't afford to make any other expenses. Plus my parents already pay for my schooling tution and it’s already really expensive, so i don’t want to bother them more. Any help would be greatly appreciated! And thank you in advance for your support.
