What is the best way to review the Noble Qur’an by myself, and will my forgetting it after memorizing it be held against me on the Day of Resurrection?

Forgetting the Qur'an and neglecting its regular recitation may be due to a sin, and some have considered it among the major sins. The remedy for forgetting is sincere repentance, piety and righteousness, contemplating the virtue of reciting the Qur'an and the seriousness of forgetting it, pondering its meanings, distributing time among tasks while allocating a fixed time for review, organizing study circles with peers, patience and perseverance, avoiding distractions during recitation, correcting the intention in seeking knowledge, gradual memorization, and utilizing modern technologies. Furthermore, associating with righteous companions, attending congregational prayers, diligently performing remembrances (dhikr), and listening to Islamic tapes are among the most important reasons for steadfastness.
