Although I've made good progress, and I think I've cracked the radial velocity calculation, I haven't quite finished TMA04 of S283 yet. It could still do with a grammar check and proofreading. I've had a look on my Study Calendar and realised that there are 44 days left until the S283 exam. It's worth keeping in mind because it gives me something to aim for and focus on.
I have also registered to study S284 Astronomy next year, and while the start of the module is a long way off (first week in October), the TMA cut-off dates have been just been published. There are six of them worth 8% each and a non-scoring TMA00 with a firm cut-off date, which is very odd as the first TMA is usually formative and optional. The two module exams take the form of timed Moodle quizzes. The first in January of one hour duration (12%), and a more important one at the end in June which I believe is a more traditional three hours (40%).
