Hi! I'm sure it will ultimately be manageable even if it doesn't feel like it...have your teachers got back to you with work that you've missed? If not, maybe you could try messaging people in your classes and get their notes/work as a good place to start. If it's too much, you don't have to do every task straight away, you could just read through other people's work/watch relevant videos/make notes and come back to consolidating when there is less going on. In regard to mocks, it's likely that you will have to do them when you get back so get those out of the way first ....try not to exhaust yourself with catchup before that. It might be a good idea to tell your teachers that you're feeling overwhelmed and they may be able to help you. I hope this helps
