If you have serious questions (which you do) then I heartily encourage you to use the forums to ask - however, are you saying you have done a complete PPL (flight training, written exams and flight test) and are now doing solo rentals - but are not familiar with how to enter controlled airspace?
No, that is not what he's saying, he's quite clearly saying that he knows perfectly well how to enter and transit controlled airspace, he's just never landed inside it before.
