@Ngaio-RO and i have both studied the training and assessment qualifications that your teachers at Tafe need to teach the classes they do. Although neither of us have finished yet, so... we're obviously not great at studying :P. Basically the teachers can and pretty much have to do whatever they can to help you get through and pass the course @j95. So like, if we can work out what you need to learn the way you like to learn, I reckon we can tell them that and get started on making this easier.
The first thing off the top of my head is figuring out what to do when you feel the stress rise beyond what's helpful over a particular piece of work, because just like being stressed about other things, the first step is to let the stress get down to a level that isn't overwhelming, and then solving the problem that cause the stress.
