Is it permissible to supplicate with the words: "O Allah, verily You are the Exalter, O Allah, raise my GPA" for the purpose of raising one's academic GPA?

The name of Allah, "Al-Khafid, Ar-Rafi‘" (The Abaser, The Exalter), is mentioned in a weak Hadith concerning the Beautiful Names of Allah. However, some scholars have counted it among the Beautiful Names of Allah. Therefore, there is no harm in supplicating with "O Allah, verily You are Al-Rafi‘ (The Exalter), O Allah, exalt my grades."
