I must admit, from personal experience, that Community College and Culinary School are nothing alike. I had more homework in my first, five week module than I did in the entirety of my college career (and I used to be premed!).
The difference is, unlike most college work, you apply all that you learn within the same atmosphere. One does not need to search for the application of the book work to real life, it's easily seen.
Of course, it is stressful but if she loves the subject enough, the stress won't really matter because at least she's learning something she wants to learn and that makes all the difference in the world.
Support is good, they say that at my school like a broken record, but it's ultimately up to her. No amount of encouragement can get someone to study, but you'd be surprised at how a little discouragement from a parent can blow one's confidence.
So stay positive!
Never stop striving to beat all expectations. Especially your own.
