Applying to masters after failing one I recently graduated with a degree of BSc in Physics, after failing a masters in physics due to depression. I have been interested in data science during my undergraduate studies and have been trying to find a job as a data scientist or machine learning engineer, but after several months of rejections, it's clear that companies don't want someone with no experience or a relevant degree. So I am pondering the possibility of applying to a masters in data science or machine learning. Is reapplying masters frowned upon? Any advice on how I can convey to the professors that I can complete the degree despite my failure?
Update: I have disclosed my situation in my personal statement. My referees have also promised to write strong recommendation letters. It all depends on my performance in the interview now, if I get one.
Update 2: I applied to UCL, KCL, Nottingham and Bristol. I received offers from all apart from UCL! I accepted the offer from KCL.
I can only speak for the UK, but in my opinion there's no issue about applying for a second master's degree. I knew two people on my MSc that had already "completed" a master's degree, and for one of them it was his third.

The personal statement is always the best way to express how you feel about the course you're applying for, but if your first degree is good, and you don't need to mention your previous masters, I wouldn't bother.

If you're genuinely anxious, you could contact the course convener and ask him/her some questions about the course and then simply ask whether your undergraduate degree is sufficient qualification. (I think you should have no problem with a data science degree if you have a physics degree - just make sure you are no stranger to coding.)
