My chemistry teacher in school got the class to copy the introduction of the main text book for the course in first class. He then took all the bits of paper and put them in an envelope with no explanation. 2 years later, at the end of the course, we repeated tge excercise and he handed out the originals to compare. He just wanted to prove that studying chemistry wrecks one's handwriting. Only one person out of 27 (think am remembering correctly) had the same hand writing. All the rest looked an absolute mess, including mine!

Enjoy the practice! PV
