Hello :)

Please excuse my teasing. My first thought was POTUS with two P's and I couldn't make that fit gardening. You are so talented with your camera, I decided to clarify your typo with my talent -- red check marks and circles.

LOL... once a teacher always a teacher.

In truth, I am not a big fan of check marks -- red or otherwise. I was more inclined to mark the correct answers with a C and let the wrong ones be. That way my students' corrected work meant more Cs and no checks to cover-up.
