Sleepyrascal. If i was you i would really really get there the evening before. It wont cost you much to change your flight and hire car and b&b is very cheap around there. It just means you dont have to get up silly early and be all drousy for the day. I really do advise it.
Im at my stage 3 now and i can say stage 2 is good fun. The pilapt tests are quite challenging in parts but at the same time fun. I cant say the maths is easy as i have to re-take myne
All the best just play lots of computer games to brush up on hand eye stuff.
