Impossible conditional acceptance?!

I've been going over my Warwick MSc conditional acceptance letter again, and it still seems impossible for me to achieve the grade that they stated. The condition on the letter reads:

"This offer is conditional upon you:
- Achieving an average GPA of 3.3 or above across all of the modules of your degree and providing an attested/certified copy of the degree transcript and certificate.
- Not choosing Economics as an elective as you already have an extensive economics background in your undergraduate degree."

Am I understanding this correctly? They want an overall average of 3.3 over all the courses in all 5 years of my undergrad degree? Because my first year was terrible, even if I finish with a 4.0 average in April my cumulative gpa will still only be 3.1

While my last three years have been very high grades, did they not even look at all my years, or consider that it might be impossible to meet the required condition? The office told me there was something like a 15% acceptance rate, so why would they give me an offer when it is essentially impossible for me to meet the grade condition?! Now I'm really starting to panic, as I am supposed to firm by Friday.

They definitely didn't mean to give you an offer which would be impossible for you to achieve, though, because that would be pointless.

There may be some negotiation to be had. An extra credit independent study perhaps? Summer school? It may be that they're only looking at courses that make up your degree. I know at my college in the USA they let some people in their 'super senior year' throw out courses as they weren't connected to their major as it had taken them so long to declare one.
Look at all the options and discuss them with your current school.

Summer school? Isn't that something aimed at little kiddies, to help them get a sense of what undergraduate study involves? Or does the term mean something else in the US?

What course is this for? Is it the diploma in Economics?

I would go with the sure thing personally, especially in such a tight time-frame. A 3.3 is usually considered the minimum standard to equate to a 2:1, so that is probably why they want this GPA.
