visa help

Hi everyone Im a bit confused about something.

For the visa I need to pay 50% of the tuition fee upfront however I cant do that until I receive a firm offer right now I only have a conditional offer and the conditions are very easy they just require me to complete my Alevels

My Alevel results will come out in mid-August If I pay the 50% tuition fee then Ill only have about two weeks left to get the visa which doesnt seem like enough time.

Is this normal?
