I'd also like to know from anyone who is doing/did Economics, German and Maths.
Probably because of parents interfering. Or picking a subject because they think it will suit their career as opposed to being a subject they like. Also maybe because of a lack of knowledge of the subject, like I know some people who instantly assumed they would love a subject without not actually looking into what it will be like or how much the subject demanded.
mainly because lots of us got poor advice from underfunded career advisors.
i had to take a gap year because of it
A lot of people choose their A-Levels aiming to get onto a particular university course, aimed at securing a particular career (e.g. people choosing Chemistry and Biology because they really want to do Medicine). And then it turns out that they aren't actually any good at those subjects, which doesn't bode well for going into a degree and/or career that heavily depends on them.
One problem not mentioned is artificially 'balancing out' A Levels where humanities and arts students feel compelled to take a STEM subject or vice versa simply to show others that they can use both sides of their brain but they dislike or struggle with the subject and also have a less than compatible selection of A Levels.
I did it twice picking up wrong A levels. I lost so much valuable time by selecting classes I was not really good at.
I wasted a year because of this mistake which I will surely not repeat again but yea it is important to get some advice and discuss these matters with some experienced people. That is one of the reasons I started reading these forums.
imo if ur not planning to go to uni a levels are a waste of time and all abit alienating. here i am studying a level english. for what? for what exactly? no value to me or employer. so ppl dropped out like flies. only 5 of us out of 35 or so from schoo got to the end. 30 ppl dead
