Borojo, DC and courses will all be different. An arts course would be DS' personal idea of hell.
The reason I asked OP up thread whether her son was taking a STEM course was for DS, year 2 exams are the ones that really matter.
The first year is relatively gentle and the first year exams don't count for a lot. Essentially marks from the four exams count as a single module. You then take four further courses in each of the next two years and your degree result is based on the best five out of nine.
Year two is a big step up. On DS' course it is where they tackle the technical stuff, which in his case includes a couple of quite tough maths modules. Year two also matters in that if he gets good results in a couple of papers, on top of good results in his first year, he can apply for jobs or post-grad confidently saying he is set for a first or 2.1.
It is made more difficult because there is no mark scheme, and often no past papers. One lecturer told them explicitly that the format of his exam would be different from previous years. You are being tested on your knowledge with relatively few reference points. It is not like school where if you are in the top half of the top maths set you can expect an A*. The material is tough, the test is a bit of an unknown and the result matters. I get the feeling that the University is also "cruel to be kind" and a fair proportion will be judged not to have made sufficient academic progress and be required to resit of repeat the year. This certanly happened to some of DS' friends last year. Presumably better that than failing the third year.
DS tells me the third year is then easier as it will mainly be options he has chosen based on the technical material he has mastered in the second. Plus if he gets some good results in his second year, and the job or post grad offer he wants, there will not be so much riding on those results.
In short, it is not surprising that a DC facing second year exams would have a crisis of confidence. How they do is very much up to them, their ability to master the material and the work they have put in. No teachers or parents to provide hand-holding.
Still, almost done here and no disasters yet. All I could contribute were reasurring texts and a small unexpected gift. But I think these were appreciated.
