Reservation fee for FEU Tech if i want to maintain my scholarship eligibility

i took the feucat in feu tech and i passed and sabi po i'm eligible for the Entrance Scholarship. i got another email saying i should pay 5k as a reservation fee for my slot and the deadline is tomorrow. do i have to pay the reservation fee agad kahit na di pa nagpapapasa ng requirements for the Entrance Scholarship? i'm scared po kasi na baka mawala yung eligibility ko if ever. thank you!
