Ppp44 - I would say this is about average difficulty. Last weeks was at the very easiest end, if you have access to that. You need a copy of the Chambers dictionary as many listener answers aren't in other dictionaries. Either the big hard copy or the excellent app (which I would highly recommend).
I found the top left corner the best way in. Maybe 1d, 2d, 3d, 12a, 21a
