Economics- alevel maths

Hi, I’ve applied applied for pure econ and had some offers back already and waiting for two more. The issue is I didn’t actually do maths at alevel and applied to the economics course which was the most prestigious and best that didn’t require alevel maths (predicted 3*A alevel which explains why I wasn’t instantly rejected as they do prefer maths) which means I still have a tough economics course at uni which will require lots of maths. I am no means not good at maths I did get a 9 at GCSE I just haven’t done it in two years. My question would be will I struggle and also is it possible to self teach alevel maths (basics not looking to score a* on past papers or anything) over the summer and if so what books would you recommend and any methods? Thanks

Yeah it’s definitely possible to teach yourself. For edexcel at least, I would say find online versions of the textbook or ask a friend if they have an active learn log in. Also DrFrost has THE BEST powerpoints for the whole a level maths spec which are very useful. Physics and maths tutor have endless questions as well so you can continually teach yourself
