i usually write down all the ones i need to do and then cross them out/delete, or mark them to be completed, then i know how many and wich ones i have left. my brain doesnt work like yours when i write down the ones that i finish, i need to see all of them and then complete them one by one

i'm not saying pen and paper is bad or anything, its fine. just in my situation it would be slower and more inconvenient
your hand writing is fine, at least its all capital letters so its much easier to read. i had to read quite a few handwritings and only few were readable to me

no idea how teachers do it in schools
