I had Colin as my instructor and can honestly say he was a great person to learn with. He is very firm when he needs to be but he is also very funny and calming and makes the learning experience perfect. Although it took me 3 times to finally pass he never gave up and knew it was mostly down to nerves he even switched my test destination for the third time to make it easier for me on the kind of mistakes I was making. Colin really cares about his students and even got me a congratulations card at the end. Would highly recommend Colin and momentum thouroughly good experience with great communication. Thank you all.
