Heidi Smith, How to Pass Numerical Reasoning Tests: A Step-by-step Guide to Learning the Basic Skills Review

Overall Rating

Contains a lot of examples - useful practice

Contains significant serious errors

Heidi Smith, How to Pass Numerical Reasoning Tests: A Step-by-step Guide to Learning the Basic Skills - I have only sampled a relatively small part of this book - the Data Interpretation questions. I've done five of the fifteen questions (Qs 3 to 7 if you have the book), and three of those have significant flaws. In some cases answers are simply wrong for the question as worded (seems possible an editor has changed questions to make them "read better" without realising that he/she had actually changed the question and had better check the answer!). In another case the answer agrees with the question, but the method in the explanation involves irrelevant information and hence unnecessary calculations.
