This is very helpful, you are a life saver!

Ilona Butt

I'm doing this exact course - thanks for all your help! AMAZING!!!

Ali

There's a LOT of spelling errors and typos - e.g. Loma prieta was in 1989 not 69, but apart from that it's great!

Mr A Gibson

Why is this good..? It is succinct, factual and useful to learn some examples from. You will not regret using this! Bet you can't remember how to spell "Eyjafjallajokull" though on number 8!
