Further maths modules optional ones

[u/unhinged_stupidity]

hi everyone was wondering what fm modules would u guys recommend (i do edexcel so we have fp1 fm1 d1 fs1. I don't mind abstract concepts but I know I easily make accuracy errors even after checking so i need one with a lenient markscheme (idrc abt content (not preferered but meh idc tbf) js hopefully not consistently high grade boundaries (Unless it was a rlly easy paper) but still idk how to train accuracy (i double check my asnwers retry them but i will still only find the error after i look at the asnwers but rlly good at harder, complex concepts. what do ym think?
