hello,
thank you very much for the information. Now from your conversation and inputs, I could make like the following -

.
1. Before going for ppl training, I better complete theoritical exams and study upfront. which will give more beneficial. I will be on to it.
2. secondly between UK and USA choise :: weather is important thing. If I am able to complete my training in short time UK is good for summer, for remaining seasons US better choice.
I am unlikely going to do in summer due to my job pressures. so, I will concentrate first on theoritcal exams, then slowly move towards practical. thank you for great advise.
