This question already has an answer here:
I am planning to attend a PhD program in the future. Should I be honest that I have some experience of attending a full-time Master degree in the past for three years? I had a somewhat rocky relationship with the thesis supervisor resulting in me being kicked out from the program. I am a bit worried that revealing this might be not too beneficial for me during the application process. Can I pretend that I did something else during the three years? In reality, I did some work in a part-time manner while attending my old program (self-employed).
