Reddit reviews Chemistry

Your best and safest bet is always buying a textbook and it's solution manual and just go through the book and do the problems
I recommend chemistry by zumdahl, it's a bit expensive but you can always rent and and pay a lot less
Book: http://www.amazon.com/gp/aw/d/1133611095/ref=mp_s_a_1_3?qid=1407886305&sr=8-3&pi=SY200_QL40

You might be able to find cheaper solutions manual, you just have to look around

Also this book I recommended is slightly higher than a level you asked for but you will definitely master high school level chem plus a lot more interesting stuff through this book

On the contrary. You can buy Chemistry.

barron's review book is good, it's also the only one I have ever used so I can't actually give a fair comparison to others.

Zumdahl & Zumdahl is a very excellent textbook (not review book). I borrowed this textbook off my Chem H teacher and read it over the weekend before the test and got a 5 (didn't take the ap chem class). It can probably be used as an alternate to a review book

From which background are you asking this? Because from a chemistry point of view this seems like a silly question because the knowledge growths and changes each day.
From the perspective of an interested citizen with the goal of an broad education a single good general chemistry book like Zumdahl/Chemistry contains enough knowledge about chemistry for a lifetime.

If you want to build a doomsday proof bible of chemical knowledge or want to bolster your library as a scientist from another scientific branch like biology or physics you could alsocome quite close to capturing the most important knowledge. For this approach I would take the existing "bibles" for subtopics of chemistry like organic chemistry like Bruise/Organic Chemistry. I would at least take specific books from organic, inorganic, physical, analytical chemistry aswell as biochemistry. Most of these bibles have 1000+ pages so this "book" with 6000+ pages could maybe contain something like 50% of the knowledge about chemistry by todays standards.

I'm not sure how much background knowledge you have, but Chemical Principles: The Quest for Insight by Atkins as well as Chemistry by Zumdahl are good general chemistry books (AP level and beyond). Zumdahl is probably better if your knowledge is starting from scratch, although I prefer Atkins.

Also, buy the older editions - they're a lot cheaper and are basically the same.

Some excellent starting books for the above subjects is as follows:

Pre-Calculus by Cynthia Y. Young:

https://www.amazon.com/Precalculus-Cynthia-Y-Young/dp/0471756849

Provides an excellent summary of elementary Algebra up to starting concepts of calculus, such as the difference quotient, etc.

Campbell Biology (10th edition):

https://www.amazon.com/Campbell-Biology-10th-Jane-Reece/dp/0321775651/ref=sr_1_4?s=books&ie=UTF8&qid=1483427728&sr=1-4&keywords=Biology

Covers pretty much every form of Biology you'll cover throughout your middle school/high school days, up to freshman year of university.

Chemistry 9th Edition: by Steven S. Zumdahl (Author), Susan A. Zumdahl (Author):

https://www.amazon.com/Chemistry-Steven-S-Zumdahl/dp/1133611095/ref=sr_1_12?s=books&ie=UTF8&qid=1483427816&sr=1-12&keywords=Chemistry

A bit more complex, however once you've gained a grasp of Biology/Algebra, this is a fine novel illustrating all the workings of chemistry you'll cover throughout high-school-freshman year university.

That's all I can really recommend as of now. I'm inclined to believe you're 1-2 grades ahead of your peers, and it shouldn't be too long until you finish up basic arithmetic, and starting learning higher maths. If you intend to develop a higher understanding of these fields, seriously try these books out.

Despite their expense, if you can find a way to rent, study, and complete them, you're basically set til' college.

Also know that these books are the most recent editions of their respective categories: These books are used in a multitude of schools/universities, not just random textbooks delving into irrelevant subjects: Nearly everything encapsulated within them is pertinent.
