Hi! I do psychology A level and the content for AQA is quite intense and I think you'd be better off sticking with your maths. If you were to take psychology instead, would you stay behind a year to get an A level in it or just take it as AS? I think if you drop maths then it's technically a wasted year as that AS grade won't really be valuable to you. But if you were to carry it on and turn it into an A level making sure it's a pass at least, it would be better. If your math skill is good and it was just the lack of revision then perhaps it isn't the end of the world and you really can transform that grade to become what you need it to. However if you feel you lack the ability to get to the grades you require for your next step then maybe it won't be worth it. Have you already got your predicted grades for maths/ is your AS grade going to affect it? I think the key differences in maths and psychology is that in Maths you're learning more methods and how to do things rather than theories and studies etc which is a lot more content to grasp. Last year we did Memory, Psychopathology (so like depression, anxiety, OCD), attachment, Research methods which is an absolutely massive topic, Biopsychology and lastly, Approaches. I think sticking with maths really will be the best thing for you considering all of this and the work you put in will be worth it. You can definitely do it but seek all the help you need with the ideal end result in mind. Good luck!
