Orientation question.

Hello all, I apologize if this is a bit long, but I need answers. Please.

So, I will be transferring to Cal State L.A. Fall 2019 and I signed up for Orientation which is in July. However, the site states that “New transfer students will register for classes on their Orientation date. Cal State LA is a “Pay First” campus, which means you will not be able to register for classes until after you have settled your student account. This means students must pay all tuition fees prior to registering for classes. We know in many cases, this can be different from your previous institution, so please be sure to take care of your payments WELL IN ADVANCE of your Orientation date.”
I qualified for grants and for a loan to pay for the rest of the cost, but would this affect me in registering for classes since I don’t know when I would receive the money or would the money go through right away the moment I register for the classes?
