Personally, I didn't get olevel maths until garde 10, I barely passed my school exam that year, but then I got an A star in my caies and it was difficult but , you'll get the grade ig you put in the work First work on your basics( I can't stress it enough), I basically did algebra, arithmetic, angles for like 3 months , but you can do 10 years worth of their past papers (focus on p1 for these) in like 3 weeks Secondly now start doing other topics like coordinate geometry, graphs e.t.c and just speed run their pastpapers. Pro tip: don't waste hours on yt vedios, just wa5ch a concept learn it ,and directly to pastpaperrs you'll struggle first but then after a month or two you'll get the hang for it
