No need to write 2 years in any case.
Despite Offer Late saying 12-24 months, right?
Also, do you know if we pay for the entire year in advance but, for any reason, decide to withdraw or transfer to another university, are the fees for the terms that I did not partake in refunded to me? I'm asking SFS too but they take ages to reply. Also asked them to give me a letter stating the tuition fee per term since offer letter is blank when it comes to fees - just says check website.
