do you redo each unit test on khan academy until you 100% or move on once you hit mastered?
i sometimes feel like i'm wasting time i could be spending learning new things and practicing questions i'm not so familiar with
what do?

I'm relearning maths before I start my chemistry course at college and I often find myself doing long multiplication and multiplying a number by something completely unrelated
I'm not even getting the numbers mixed up on the page, it's like I read 5*9 and do 5*7 instead
i also end up thinking of a number to write down before writing something completely different that seems to come out of nowhere
i can remember long strings of digits well and don't misread them so i don't think it's discalculia
it's making everything incredibly tedious and frustrating
even when i go back to check my answers it's like my mind is still dead set on the wrong digits for some reason
is this a relatively common phenomenon?
how do i stop?

how do i think for myself?
