WHILE there is a next sentence to read, DO: BEGIN (* while *) Read it, SLOWLY; IF you do not understand it, THEN BEGIN (* if *) re-read the previous material, SLOWLY; re-read the incomprehensible sentence, SLOWLY; IF you still don't understand it, THEN ask a fellow student to explain it; IF you still don't understand it, THEN ask your TA to explain it; IF you still don't understand it, THEN ask me; IF you are in an upper-level course & you still don't understand it, THEN write a paper about it (!) END (* if *) END; (* while *)Since there is no next sentence (because the Boolean test in the WHILE is false), you've understood the text!
