Is there a prayer for academic success?

There is no specific supplication for seeking success, but a Muslim may supplicate to Allah for success and facilitation in any way they wish, as long as it does not involve transgression in supplication. It is recommended to supplicate with the supplication of Musa (peace be upon him): "My Lord, expand for me my breast [with assurance]. And ease for me my task. And untie the knot from my tongue. That they may understand my speech," and with the supplication: "O Allah, there is no ease except in what You make easy, and You make the difficult easy if You wish," to facilitate matters.
