If I get you right, you enrolled because of the opportunities that the programme offers and you are considering quitting because of this one teacher.

First, choosing careers that does not align to purpose or passion is one of the major causes of disinterest or unmotivation and regrets later on in life.

My honest advise is that you quit if this programme does not align to passion (things you are gifted or talented in). I know you are passionate about the incentives that certain careers promises, however, you need to come to terms with the fact that the only formula to success is being the best in whatever thing that you do and passion is the number ingredient because success is hard, if you do not love what you do, you will remain a mediocre or quit along the way.
