I think this is probably the best IB chemistry book out there.
Extremely high quality with very comprehensive explanations and examples on how to solve questions!
There are "Challenge Yourself" questions that serves as a great checkpoint that you have fully understood the chapter, so keep an eye on those!
I really liked that our school used a study guide from a different publisher from the course book.
This introduced a new perspective on tackling concepts and solving problems for me.
I definitely recommend this study guide.
Our school did not use the Chemistry Course book by Oxford, but we used the Biology book by Oxford.
So I imagine if Biology book held a high standard, I think the Chemistry version will also hold a high standard.
