I don't like these options

So, here's where things stand at the moment:

I decided that I could handle three subjects a trimester this year if I switched to part time.  I have previously been able to manage two subjects while working full time, I couldn't see that this year would be significantly different.  I figured I could take the last three subjects to finish off the DipModLang while taking three subjects to round out the first year of the MAAL.

I discovered a slight problem, though:  I'm not good enough for one of the subjects.  I took "business German" for the sake of growth, but I haven't "grown" enough in the past two years to be able to take it in my stride (instead, I'm stumbling after it in a strange, limping manner).

It's going to take twice as much time and effort as I had predicted.  I possibly would be okay with the juicy new challenge, except that I've cut things too tight and I'm not good enough to cope with a subject that's soooo much more of a challenge than I was expecting.

I realised this in Week 2.  I quickly took a look at the other German Language subject I could have been doing instead of this one, and worked out that it was more within my current abilities.  I could catch up on that subject more easily than I can keep up with this one.  I asked the coordinators of both if I could switch.  I spent most my study time that week getting a leg up on the new subject.  I went to enroll in the new subject...

Only to be told it wasn't permissible.  The University of New England (UNE) does not allow subjects to be added to your enrollment after Week 1.  You can dump a subject, but you can't take on a new one.  It doesn't matter if you're only in the 3rd week of lectures and haven't had any assessment to complete yet.  It doesn't matter if your subject coordinators think it's entirely fine.  If you hadn't decided to change in Week 1 you don't get to change at all.

This is several shades of stupid.  You don't know what a subject is like in Week 1.  You can't make an informed decision about whether you have chosen the correct stream based on what you discover about a subject in Week 1.

I was informed, in no uncertain tones, that unless I had been the victim of a natural disaster there would be no flexibility on this.  I either stayed enrolled in this subject or not - there was no chance I would be able to take the other subject at all.

Problem with this is that the subjects in Trimester 1 are prerequisites for subjects in Trimester 2.  Even if they weren't, I can't make up this subject next Trimester - it's just not physically possible.  So, this means I either do this subject (which I'm not smart enough to do without a tutor - and if I'm going to hire a tutor, I may as well just drop the course and study privately), or I add another year to my degree.

That's right, folks.  If I decide that I'm not going to spend time and money on a subject that is not right for me, I can't graduate this year.  This is despite the fact that there is another subject I actually could be doing if I was only allowed to enroll. Thank you, University of New England.

So, these are my options:

1. I push ahead, even though that would cause all three of my subjects to suffer as I will be struggling with one so much that I'll be stealing time from the others.  I don't like this option.
2. I unenroll in the problem subject and change next Trimester's subject to the only other subject I will be physically capable of enrolling in (film studies - which wouldn't be too bad, but it means I will be missing out on a Trimester's worth of language education), and then complete one of the language subjects next year, when I was supposed to be concentrating fully on completing a Masters degree.  I don't like this option.
3. I unenroll in the problem subject, and just don't enroll in anything else.  I finish the short stories subject (because I've been looking forward to doing it for the past two years) and then terminate my enrollment in the DipModLang - thereby dropping out of a three-year course halfway through third year just because I wasn't allowed to change subjects in Week 3 of Trimester 1.  I don't like this option.

Thank you, University of New England.  Your care and attention to the needs of your students is... let's say "exemplary".
