This is not about whether your first solo should be to a full stop! Mine 25 years ago plus was to a full stop but I did nothing but touch and goes with my instructor until he was happy that in the event of the worst happening I was equipt to deal with what occurred with a reasonable chance of handling it. Some students are very competent and confident. I remember 1 who when told to do one circuit to a full stop took it on himself to do 3 touch and goes.
At the end of the day we are all different! But in this thread it was indicated that some students had never done a touch and go before first solo which in my book is very wrong.
