In all the maths courses I've done so far I've got either a pass 1 or a pass 2, but if I manage to scrape through to a pass 3 here (which I'm hopeful I have - I reckon I'll come in at about 60%), I'll be more proud of that than of any of the other results I've achieved. A lower second will be good enough for me for this. :o)
It's a bloody hard subject, but also very worthwhile. I've read pop science books about quantum physics before, but doing a course where you get down to the brass tacks of how the mathematics of it actually works - which in itself allows a firmer grasp of the whole thing conceptually - is incredibly rewarding. And it's given me renewed astonished respect for all the people who came up with it in the first place. It's tricky enough following this stuff; it must have taken considerable genius to have come up with it in the first place. But without those geniuses, much of the 21st-Century technology we enjoy today would never have been developed.
And now I'm free! And have had a bottle of wine to celebrate. :o)
