In college Intro to CS was taught with Racket (a lisp) and we even had to write code with pen and paper during our exams. Got really good at quickly visually matching parentheses which is still helpful to me today in non-lisps. (But given that the handwritten code would never be run, you could also just fudge it and write a bunch of )))))'s at the end and hope the TA grading it wouldn't count them either)
