Much easier to email the whole unit when you finish it then you get your grade within a few days
We have some students on an e-mail system for assignments and others on the online submission system, so you should always follow the physical course guides you received with your materials. These will tell you exactly how you should be submitting your assignments
For the online submission, you can upload assignments as you move through the course, but you won't be able to submit them to your tutor until the whole unit is completed.
I hope this helps to clarify, please don't hesitate to get in touch with the school should you need any help along the way
