I was you back in 1983. 80 total hours. Porpoised. Flat nose tire. Broken runway light. Towered airport. Certified letter some time later from the FAA advising me of a 609, now 709 review. Bummer!!!! Appointment at a FSDO with an inspector later that summer. With my ticket on the line, was it scary? Yeah. I passed.
Go up with a seasoned instructor, like I did, to critique your landings. Like me, that was where the incident occurred so that is what they will be checking. Sorry to hear.
