Ahhh, if it wasn't for BoS I would always forget to check things like this.
From the information I can gather, it looks like I'm to have my first double exam in my student career. Fortunately, the 2 units corresponding to that particular date I regard as relatively easy so I have to say I'm not too stressed about allocating equal amounts of study in that case.
