General ACCAHelp Needed - Foundation Level

Hi Everyone, I am thinking about registering with ACCA and start studying at home with the help of open tuition and the exam kits. I haven't got many qualifications so I decided to start with the Foundations Level. I'm a bit lost with foundations and fundamentals, and a bit lost on the forums. I want to start studying FA1 and MA1 to sit this two exams in December. I've read I can do this exams computer based and not only in December and July, but when I was checking the dates available for these exams on Kaplan financial website I only found available dates for December. I want to sit these but I don't want to wait until July next year to sit the next exams. Have you guys done this exams as computer based exams and where have you sit it? do I have a deadline date to apply to sit these exams in December? Every help will be much appreciated!! Many Thanks.
