i a diploma fresh grad-soon-to-be, imho this dip is worth taking IF you want to enjoy the easy college life before working. Practically what you learned in college will not really play a good part in ur future, reason being you need to adapt to their working style, that being said, learning everything all over again. Bear in mind that this route youre taking is hectic, stressful and you must physically and mentally strong, expect that during your time in college, because in the real world, its a different story.
With your diploma you will start at commis, like any other people w/out diploma, that explains why I said taking this course is to enjoy live in uni

I believe if you have the passion for what you do and give your 100%, people will appreciate you. I've been shortlisted by my internship chef to work in the new restaurant outlet alongside with him when I graduated, as a Demi Chef which I think is a good start for a fresh grad. So think twice if not thrice before taking this path, if your direction of life is only towards the money, I shall advise you not to take it because ive seen people going from culinary to telco promoters, properties agents etc etc where money comes easy

interest and passion in cooking is two different thing, one is a preference, one is a job for life. Good luck, I bid you good eating
