Substitution Strangeness

With T224 coming to an end, I’ve been playing around with Marx and the OU’s own Assessment Calculator to work out what I’ll potentially need to get a distinction on the course. With T224 not counting towards the honours calculation on the degree I’m working towards, the pass grade isn’t really important as such, but there’s a level of personal pride there that makes me want to the top grade. Start as you mean to go on, and all that.

I’m currently waiting on my mark from TMA04, but depending what I get there, the substitution system is throwing up some unusual vagaries that seem to flow from the different weightings on T224′s assignments (TMA01 15%, TMA02 30%, TMA03 30%, TMA04 25%) that could leave me needing a very specific mark on the exam (85%) to guarantee a distinction – any lower and the OES is below the threshold, any higher and the substitution score switches to a TMA with a different weighting and leaves me short on the OCAS. It’s all theoretical at the moment, but I’ll be looking into this a bit more once I have my TMA04 score, as I’d consider the possibility of getting a Distinction for scoring 85% in the exam, but a Pass 2 for scoring 86%, to be something of a glitch in the system…
