Because of my circumstances I did my mod 2 the day after my mod 1, but it was a risk. I basically did mine on holiday! I went to stay with my mum and step dad during my summer holidays and my step dad paid for me to do the CBT, it took me a week to do that, as I had never been on a bike before. My instructor then did a week with me on a bigger bike, an hour or two a day...it was exhausting and my concentration used to go. I think I dropped the 500 twice and he threatened to put me back on a smaller bike!!!! After about a week and a half of riding round and praticing for mod 1 - i was lucky bacuse the centre i was learning at was also where the mod 1 circuit was layed out - I then did my mod 1 a day before I flew back home (with the intention of taking mod 2 in the october half term) I failed it due to nerves so in the end, booked to come up in Octobe for 6 days, spent 3 riding round and practising mod 1 then took mod 1 the morning before I left (was supposed to be the evening before but by then it was getting too dark to do it) and the took mod 2 the day I flew back out (honestly I had 2 hours to get the plane after i passed!!!) Luckily for me I passed both, but I don't recomment it, my step dad was paying which added extra pressure i suppose, but in my case it focussed me. It's all down to the individual and the centre. My boyfriend did his with only a few hours experience on a 500 because the centre said he was a natural rider and again we only had a tight time frame (good job he's good) We don't do things easily. We were lucky his centre had time and space for him. If you fancy doing a holiday and doing ur mod 1 and 2, go to Kirkwall in orkney and look up Bikewise and a bloke called Graeme. Perfect bloke and teaches you properly! Plus less of a queue for tests (although you need to go up at the right time) and a lovely holiday with challenging riding condidions to start you off!
