This affects you a whole lot more than you probably think. Someone was telling me of a very very experienced rider who hadn't drank much all day and clocked up a lot of miles, then attempted a silly overtake. Make sure you have a good breakfast and take advantage of any free tea and coffee going at the training centre! I don't think this is very good of the school at all, especially if you have mentioned that you will be riding a geared bike. The whole point of the CBT is to ensure you have the basic skills needed to safely ride a bike on the road. To me, it feels they are trying to rush you through and get rid of you even though they are aware that you do not yet have the skills to safely ride on the roads on a geared bike. It isn't a test and there is no embarrassment at all at not being able to do it immediately - however if you are not confident after completing the training then it's all a bit pointless. I would seriously consider talking to the school and mentioning this, if they do not seem to be taking your safety seriously then I would consider going elsewhere. Just my two cents! It's dangerous out there on the roads on a bike. I did my CBT on a geared bike and had one to practise on but I think I just pootled around carparks and local roads (I was insured!) for a couple weeks before I really felt ready to tackle the commute (on the north circular which is a learning experience ) Anyways bottom line don't give up and keep us updated
