don't worry, you are not probably the first student in your area. controllers are used to know callsigns of all trainers around including voice of all instructors. They will know you are rookie before you finish your callsing
Expecting you are flying from Info or Radio airport so even with AFIS you're the master anyway and they are providing just info
I said hundred times some nonsences or incorrect info into radio, heard hudred times other people do the same, including military pro etc.and I am sure I will do some more
my first solo after solo circuits so away from airport with ssr play and freq. changes was full of radio mistakes including setting wrong squawk I was asked (and confirming complete different code
and it was fine, I was just corrected after almost every word I said, feeling everyone is now aware there is moron in the air
