good luck to everyone who is using this to help with exams, quizzes, and tests.

i swear- when this is being taught in class i get so confused and end up not understanding anything, but watching an almost 10 minute video made me understand it much quicker.

MR. Organic Chemistry Tutor, thank you for another off the chart's video/lecture on Multiplying Rational Expressions in Algebra/Algebra Two. There is high probability of making errors while multiplying/factoring rational expressions, so students must pay close attention to all algebraic operations.

today is the day before my algebra 2 unit 2 test, one of the most difficult algebra tests i have yet to take. it is around 85 points for this first section, and i was really stressed about it until i remembered your videos. my teacher is rarely at school, so often, the most important lessons are taught through google classroom and a worksheet. i find myself pulling my hair out trying to teach myself these things, so when i find a video you make on the topic, i am flooded with relief. i have been on an algebra 2 video binge for the past few hours, and i have learned more from you than i have this year. thank you so much. you help so many people, including myself.

Thank you so much, none of this makes sense until I go to youtube. Crazy how much can understand in 12 minutes of youtube vs 1 school hour of staring at my desk.
