How can I convince my mum to let me leave school during the first 2 weeks back? (I have a job and just want to study something I love)?



Hmm. Answering this is difficult, especially in terms of the "how", since none of us knows your mother's personality or reasoning behind her decision. I personally would not skip especially those initial weeks, but you may have an idea or plan of action you wish to take. My questions are reasonable, then: How much of those two week will really, absolutely be spent on studying? What are the expected merits upon completion, and is this merely an interest not thought through, or is this gesture part of a devised strategy to curate a successful future? Is this time to "break", or time spent completing school studies whilst home?
