Haha don't worry it's fine
Degree wise, I've changed my mind a lot, but for the most part it is usually a Modern Languages degree I'd like to do. I've thought about French and Spanish, Spanish and Russian, French and Arabic, and everything in between. Other than Modern Languages, I've thought about Law, History, Politics, English Literature and even Archaeology. This probably doesn't help that much seeing as though it's such a broad variety but hey ho.
I don't have a clue what I want to do after though. Something where I can travel in my job hopefully, so maybe a diplomat or something along those lines. If the degree goes well, I might do a postgraduate but that really depends if I want to strap myself down to another few years of education.
If you're going into A Levels next year like me, don't worry if you haven't decided what you want to do yet. A lot comes down on the subjects you enjoy during sixth form, so what you might have your mind on now could change come 2 years.
What A Levels are you doing?
