If I am being honest it’s fairly easy to get a grade 6 in maths ( trust me bro I didn’t revise at all and I got a good grade) .
If my fat ass can get it then so can u mf.
Anyways, if u retake, u have to do the exam next year which me u have a lot of time….use that time wisely ….
Watch ALL of GCSE maths tutor video and u are guaranteed a good grade..
Oh YH after watching a topic on his channel go do topic related questions. After finishing all the topic do past papers ( in exam style).
Mark the papers and check where u went wrong.
Keep a file of the questions u got wrong and retry them until u get it right.
Btw…if u ever need any resources ask me, my skl gave me like books after book on specific topic (+ they are exam style and are also from past papers )….and yhh all the pages are blank cz I didn’t do any **** but I can take pictures and upload it for u lol…
Anyways, good luck mf
