Thanks

I am a sophomore at Rice University. I love Khan Academy, as it has helped me in my classes from high school till college, especially in chemistry and biology. It explains things in a simpler way than many college classes and can help me get ahead as well. That being said, I wish there were more courses of higher level sciences like biochemistry and so on. Also, I would appreciate practice problems in the organic chemistry section, seeing that it is such a popular topic on which students struggle a lot on. 

Thanks so much
