Khan Academy's free chemistry course, a collection of short video explanations and practice exercises that cover chemistry topics broken into small, selectable pieces.
One commenter suggests it for getting up to speed on "just chemistry" and says the explanations are pretty good and easy to pick from by interest.

I recommend not just any chemistry course but specifically this one:
MITx 3.091 "Introduction to Solid State Chemistry"
https://www.edx.org/course/introduction-solid-state-chemistr...
It's "archived" - good enough, everything is accessible, you just won't be able to get a "grade".
It's the gateway to "materials science" too. It is more at the edge of chemistry, towards physics and engineering. Not to mention that the teaching in this course is pretty good. Also, it is not dumbed down, you can go to MIT, take the same course and feel right at home. It's about properties of materials as a consequence of the chemical/physical properties of the components (atoms/molecules) and how they are structured (example: diamond and graphite are both made of carbon, then why are they so different).
If you want to get up to speed on "just chemistry" try Khan Academy, their explanations are pretty good and you can easily select what interests you because it is broken down into many small pieces.
