You have worked out your finance to survive the study.
I hope that your family can tide you over this period or you can
perform some part time to cover up the living cost.
As for the preparation, you have to start to hit on the books to
tune yourself up for the fast phase of studying.
You have to sacrfice lots of your personal and social time so
that you have more time to focus on your study.
If possible, try to stay in a hostel.
You have to gain the understanding of your bf or gf as you will
spend less time with your loved one.
Since you are already enrolled, my advice to you is to fully
focus in getting a good degree so that it will help you in securing
a job later.
It is LOTS of hard work but the effort is worthwhile as your
income will be increase to a certain level and it will allow some
spare cash to achieve your financial independence if that is one of
your goal.
