Why review books?
Students and parents often buy several resources that perform the same job while missing the resource they actually need. A good recommendation should consider specification fit, explanation quality, question design, answer accuracy, timing and whether the school already supplies an equivalent.
Editorial position
Reviews are independent. Affiliate commission may be earned from some purchases, but books are selected before links are created. Weaknesses, errors and unnecessary sections are stated where known.
Private tutoring
Torben's separate tutoring service is available at A-Level Chemistry Tutoring. The resource recommendations on this site do not assume that a student needs private tuition.
