احسن الله اليكم , Ustadh, a person while he was memorising the Quran, the teachers and he himself marked on the pages of the mushaf with a pencil. He wasn't sure of the ruling at the time, now he learned its impermissible, should he remove all the marks from the mushaf? جزاكم الله خير

Ustadh AbdulAziz al-Haqqan

I am afraid you would damage the mushaf more by removing, just from now on don't make any marks.
