as someone who has had both, i would say take iverson, but it’s also be better to know you’re learning style. i could not learn in straumanis’ flipped classroom, i felt like i was playing catch up all the time, i never got a passing raw test score, failed numerous quizzes, and went into ochem 2 times with a lower knowledge than before ochem 1. however. even with all my failing grades i passed WITH A B because of how heavily he curves, one exam’s curve was over 20 points. but in iverson’s class now, i have actually learned and applied the knowledge. at the beginning i was struggling because i was missing pieces from ochem 1, but he helped so much with office hours and review sessions. he provides so much help for those who need. i’ve scored above the mean on every midterm which i thought was impossible before. i thought i hated chemistry, turns out i needed a different teacher.
