I am asking this as they request signing a firmly offer and sending it through post which implies some sort of commitment comparing to a online confirmation.

I should sign on some conditions which are: acceptance the offers, acceptance to pay the fees, acceptance all decisions from the programme, and cancellation only in case there are serious excuses which should be accepted by the programme.

Any of you know more on this topic? I would really like to say yes but as I need securing funding or scholarship and they told me that I should send the signed acceptance and pay the deposit and in case no scholarship, I can cancel my place and refund the deposit later.

So, I am asking if there are any responsibilities in case I signed the document and send it to them like asking to pay the fees or causing problems to me in any future applications to universities?
