List some valuable online resources

[sahilmm15]

In my previous post I asked about some science documentaries to which I got some really fantastic recommendations. Also @jedishrfu listed a very helpful website mathispower4u.com. It covered each and every important concept till high school level and the basics were also quite helpful. So, what I observed is there could be many more websites or online resources for other subjects as well(physics, chemistry,etc..) which I don't know. The mentors here are very experienced and they know the web incredibly well. So, listing out these resources would be quite helpful for me and other people here on PF.

Sadly the ones I mentioned are by far the most popular lesser known ones don’t have the same pedigree and you won’t know how good or bad they are.

Although videos and tutorials are nice. They should be used as supplements and not the main study tool. Reading a math/science book is the best option with other resources treated as auxiliary.

I found professor notes helpful ( in most cases) those found on universitiy. This is too advance for you at this point, but something to consider. I extremely enjoyed the notes that Mathwonk has written and shared with the public.

there's also the maa website for book reviews. I tend to take some of them with a grain of salt, but good for an overview of the textbook and what a more seasoned reader considers the strengths and faults with the book.

Maybe someone else can chime in here, but there was a nice website that allowed users to practice drawing Lewis Structures and other chem related stuff.
