Self teach it this summer, get the Phillip allan workbook and textbook, you'll enjoy it. It's fairly easy but as you've probably heard the exam technique is hard not in the sense you require English and stuff but you have to know what they want so you can get the marks, KAA & evaluation, structure in terms of English will only get you a few marks but getting those marks for knowledge, application, analysis and evaluation is the crucial part and knowing how many marks for each of those per question is the hard part especially with the new changes to a level we only have one sample paper and mark scheme so there isn't much out there on the exam format for the new spec.
And the best part is almost everything links to together in section B, pretty much everything you learn will be a relevant point so long as you can put it into context
P.S don't do Business with economics. Business is a boring a level and is useless with economics imo and many uni's opinions.
