Please Don’t Ascend During Final Exams

One-sentence premise: In the final semester of senior year, the protagonist’s deskmate says she is actually the greatest sword immortal in the immortal realm, who failed her tribulation and fell into the mortal world. The protagonist half-believes her and follows her in cultivating immortality, only to discover that not a single student or teacher at their school is normal.

Core conflict: The day of the final exam is also the day the protagonist must undergo tribulation and ascend. How can they answer exam questions while battling the heavenly tribulation, all while dealing with the immortal-realm forces who have come to "guide" them?
