Pattern altitude: Not 10100 feet.
Left downwind: to the right of the runway. Left/Right traffic is the direction of turns made, not whether your plane is left/right of the runway.
Go Around: Announced when aborting a landing. It does not mean “I’ve landed and am doing a touch & go.”
Request frequency change as soon as you can slip a sheet of paper between your landing gear and the runway: Chill. You’re still in the airspace. I may need to give you further instruction, since turning directly into other traffic is not something easily avoided without explicit “extend upwind” instruction, apparently. [Really, how many of you have been in a wide-body jet and turned over the ramp at takeoff?]
Calling inbound: As stated above, Inbound on the ILS when actively vectored for ILS Intercept by Approach (not RV, not FF, not absent approach while 25 miles away abeam the tower). But there is another common error: reporting your position as you would on Unicom is not the same as Call Inbound. [80 percent of the time the leg reported is wrong anyway, which is just mind-boggling.]
Switching frequencies at will: Never okay
Trying to pull one over on Tower after handoff from Approach: If Approach clears you for 27R, don’t call into tower for 27L. Approach put you where they put you for a reason. Stay there. If you choose instead to cut off the pilot who was cleared for 27L, don’t cry when you don’t get to land. Just follow instructions. It doesn’t matter which runway you put in your FP 4 hours ago.
Exit and cross: Means what it says. Don’t exit and hang your tail in the runway holding short of the parallel runway and ask ground to cross the runway you were already instructed to cross.
Requesting takeoff when 4th in line: Yeah, I know where you are in line. I’m not going to get confused and let you pass through the three ahead of you. So racing to request takeoff makes little sense.
Random 360s at intercept: If you can’t get down in time, two things. One, learn how to descend. Two, you can’t be doing random 360s at the localizer intercept and interfere with the traffic that did get down in time. Fly a full go around. This means you fly runway heading all the way to upwind, then turn to crosswind. You do not do circles at the intercept point.
If you’re newly Grade 3, I beg you to watch the tutorials. The little games that get played on TS don’t fly on Expert. If you don’t want there to be a week between your first and second sessions on Expert, prepare yourself.
Finally, saying “I’m sorry” when what you mean is “damn, you caught me” does not allay my frustration or assuage your guilt. You know you need taxi permission. Don’t play games.
