Question for people who got the scholarship with MPs 18-30

i got the mp 22, and im really grateful alhamdulillah. since a few ppl top 18 ppl leave every year, can i be fairly certain that ill get the scholarship with my mp. ive heard it goes to atleast mp 25 every year, sometimes even 30-35. if anyone has gone thru this, id rlly appreciate more details like till when did u get ur refund and other misc stuff.
