    I have to agree with most of the comments on here, your instruction has been instrumental in my success. My chemistry teacher was so disorganized / his writing was so illegible, that I dropped the class to do it self paced. The course material is full of errors, the instruction is unclear, and most of the concepts that I struggle with are made clear via TH-cam tutorials like this. Thank you for putting this stuff up, we'd be lost without some proper instruction. So many insufficient grades have been avoided thanks to your selfless contribution to free education. I feel bad that a disproportionate amount of financial remittance is going to teachers that simply aren't able to teach this material to students while people like you help keep students heads above water.
