He really wanted his students to learn and do well in math. When I had him for Algebra 1 back in 2008, he told the class to always trust the formula, no matter what. Trust me, he's right. Great teacher, and even better person.
Ronny is the best teacher ever! even though he roasts me, he is extremely funny and deserves an award!
Worst teacher EVER! If you have him for Algebra I, prepare to recieve an F and 5 minute lesson lectures.
