I think I messed up my enrolment?

These are all things you need to speak with representatives from your university about, not a collection of random students/other on the internet.

However, if you are a UK student who has applied for funding from SFE, they pay your tuition loan directly to the university, and if you have applied for a maintenance loan in addition that is paid to you - you don't need to pay anything to the university for tuition yourself if you have SFE funding. If you're an international student then you need to work out with the uni how you are paying the tuition fees.

Either way, you need to speak with the university directly, as a matter of some urgency.Call them.

Cut me some slack I’ve been in a Dutch hospital for weeks. September came by so fast. I’m going in tomorrow. I was hoping for some peace of mind that I’m going through late registration instead of my placement being terminated

There's no slack involved - only RHUL can help you really. Are you a UK student?

I am

If you are self funding then you need to confirm with them that you are paying the correct amount and that they have received it, or else they can terminate your place.

However if you have appropriate extenuating circumstances (such as being hospitalised, and you the relevant documentation to confirm this) I imagine they will be happy to help accommodate you and assist with any issues in the enrolment process.

I wouldn't suggest "breathing easy" or taking any peace of mind until you have confirmed you have been successfully enrolled on the course though.

And have you applied for SFE?

No

I'm only paying my tuition now--and that's the first installment I'm paying. It isn't on a payment plan because I have no idea how to set one up. I think the deadline is today but it won't be processed until tomorrow, I'm guessing?
Also I missed today. Am I supposed to attend an Identity Check this week? I heard you need to pay your tuition before you do. Am I eligible o am I too late?
