Congrats! I did the very same thing on my check ride when he told me to do a short field landing, it was at my home field and I did it the way we always practiced, he had me go around and do it again.
Started in November 1982 school had a solo deal for $250 that included the plane and instructor for 10 hours or solo plus books, the plane was a Tomahawk. Soloed at 9.6 hours, could have done it sooner just wanted to get all the hours I could. Changed over to flying a Warrior after solo, it...
My CFI told me if we lost the engine to wait untill we were 200 AGL to turn the landing light on and if I did not like what I saw then turn it back off.
