hiii!! i do health and social care btec which I started in september (as well as geography and english lang alvl) so it's really the only one i can give my opinion on!! it's a really nice class which I enjoy a lot. but i think if you don't like coursework it may not be for you as it is VERY coursework heavy!! we learn a lot about different life stages and the issues that come with each of them as well as growth & development + physical, intellectual, emotional & social factors that influence one's mental and physical wellbeing. I find this really interesting and agree that it does tie in nicely with medicine so it could look very good for u
as for sociology / criminology - i'm not a professional but i have a friend who does both of those along with law. she really enjoys them too but similarly with h&sc, criminology has a lot of coursework. but since u mentioned wanting to do forensics i have to say i don't rlly think that criminology talks much about the forensic side of crime. it's kind of similar to law (from what i've heard from friends) i think it would be worth looking deep into the course, exam board and course details that ur college provides.
finally, i just wanna say that ik it seems like this is a rlly super huge big decision right now but trust me this isn't final!!! don't worry too much :]]
I actually switched from fashion and textiles within the first few months of A-levels and was able to catch up in Geography which is what I switched to very easily.
to wrap this up, I'll say in my opinion health and social care is probs ur best option tbh but then again, I am not a professional and still think that u should gather as much info as u can before making a decision ! remember !! : u can always change within the first few weeks/months depending on ur colleges rules.
hope u do rlly well on ur GCSE's + good luck in deciding what you want to do in colly xx
do NOT stress ! it will b okay x
