What are the aids, supplications (duas), prayers (salat), or Quranic surahs that help strengthen memory and recall, especially in academic study?

Inability to memorize and focus can be due to organic diseases, worldly concerns, psychological pressures, sins that cause one to forget knowledge, or the evil eye and magic. It is recommended to consult specialists, perform Ruqyah (Islamic exorcism/healing), and supplicate frequently. Remember that these calamities are trials that necessitate patience.
