If you only did section A this sits you are a maximum of 40/80, or 50%. Assuming that if you spent 2:15 on Section A it's going to be reasonably good this might give you a D/C I guess, depending on the leniency of the grade boundaries.
If you're lucky it'll equate to a C, as the coursework B may drag it up, although because of the weighting it'll be pretty close I fear.
