Grades subliminal plsss!!

Okay my exams are coming next week and I desperately need good grade subliminal!!! Also I have been using subliminals on and off for a year. Last year for my exams i listened to subliminals and got the freaking results 8.5. but the thing is after half a year my uni was like the results were wrong there was some mistake in the system and dropped my grade down to 7.5.

PLS give me grades subliminal which gives permanent results 🙏🏼🙏🏼
