As a user in the UK I find it hard to understand what level the different videos, tests etc. are meant for as they're in the American grade system. Could you introduce a feature for the UK where the videos, tests etc. say what level they're meant for in the UK (e.g. Key Stage 1, 2 & 3, GCSE, AS Level and A Level)? Khan Academy is an amazing learning source and this would make it even better for us brits! Thank-you so much for the brilliant work all you guys do!
