Excited but Worried

Geeze, I've forgotten to email Dudley College. I never opened my blog to see what I wrote last night. *tsk tsk* So much for a reminder.
One good news is I've received a reply from the distant learning Oxford College. They say all these online courses are available for international students except Chemistry and Physics which apparently require you to do researches and experiments in a laboratory. I took Chemistry, so there's no point for me to re-take it. As for Physics, it's always been my nemesis. There's basically no mutual affection between us :P .
The matters left unclear and unresolved are for me to find a local school/college and contact them or the British council as a private A-level student for an exam placement, and to find where to pay for my exam fees. 
The other thing is to prepare documents of my high school qualifications and perhaps along with my IELTS certificate for enrolment. One last problem is MONEY and PARENT PERMISSION. *sigh* So many things to plan and do. My first priority is to do IELTS revision and register for an IELTS exam that is scheduled at an earliest time possible, so I can process my enrolment soon after that. Other than that, I need to gather more information on these distant learning courses. They are expensive though not as much as actually studying abroad, still a lot of money is needed.
Anyone with an interest in these courses can have a look HERE.
They offer a variety of subjects and qualifications.
I'm considering to take two or three of the following courses:
1. Ancient History
2. Critical Thinking
3. Environmental Studies
4. Psychology
5. Sociology

I'm still undecided. All these subjects are very tough for a non-native English speaker and require extensive literary and communication skills. I don't know if I'm good enough, but I'll do my very best. 200% of my efforts.
I am at the same time excited, hopeful, but dubious and anxious. I don't want to plan out everything only to find out that it won't work for a Vietnamese student living in Vietnam. Regardless, I have to do it for a better future. I"LL DO IT.
Once I've gathered enough information. I'll break the news for my mother first and leave it to her to do the same to my father. I am not in good terms with him. My mother will be our liasion.
