The TT courses have developed something of a reputation of slipping up with the assessments resulting in numerous questions needing to be “zero-weighted” ie not counting towards the final mark.
It looks like the first CMA of TT281 is continuing in this tradition. In TT280, the preceding course, the marks for the three CMA worked out to have around 80% of students achieving the top grade and 15% getting the next highest grade ie a total of 95% or so getting grades 1 or 2. For the first CMA of TT281 the figures are rather different with only 18% getting that top grade and 61% getting the top two grades and 89% in the top three grades. Overall, it looks like most people have dropped something like 20% to 30% in their marks which is pretty bad.
The reason basically is down to a combination of rather less clear questions and what appears to be quite a high number of iffy “correct” answers. In my own case I count six where the “correct” answer is rather iffy and three where it’s definitely wrong which equates to over 20% of the answers.
Naturally a lot of people are currently fuming about this. The response from the course team is that the explanatory paper will be released sometime next week. Somehow I think that’ll spark even more argument if a whole raft of the questions aren’t zero-rated.
