Well, I'm down to three subjects and although that means its less likely for me to finish in 2019- I feel alot better and more confident in my studies. Like a burden has been lifted off. It's nice having time to pursue things I care about also.
I think everyone feels behind / overwhelmed in first year, and there are some things you can do: take less subjects (there is no shame in dropping. Best to do it before census date so you don't have to pay!), use the two-week gap for massive catch-up. If that's too far away- you won't have university from Good Friday to Easter Monday because of public holidays. Good Friday is such a great day for catching up and studying: every store is pretty much closed and if you are in a religious family, like I am- it is considered a valid use of time.
So if you don't want to drop any subjects, look into developing stronger time management skills. This can be done by drafting study timetables, talking to an academic advisor. Good luck Snowflek!
