Not OP but I am an abnormally good "tester." It was always easy for me to see what the questions were asking for and could make a go of anything multiple choice. I'm also good at writing essays. It does not make me smart, it makes my abilities especially suited to standardized tests.
If you cannot solve the same problems given an open ended question, is it real ability? There is definitely something there, but Iām not sure I could be proud of it.
