Our rankings are cleverly generated from the algorithmic analysis of thousands of customer reviews about products, brands, merchant’s customer service levels, popularity trends, and more. The rankings reflect our opinion and should be a good starting point for shopping. By purchasing the products we rank, you’ll get the lowest price we found while we may receive a commission at no cost to you, which will help us continue to provide you with value.

How do we rank
Our AI-powered platform ranks products using multiple weighted factors from millions of products and user reviews across the web, providing the most valuable and real data. Higher scores rank first.
Harder Questions: The questions in this level are more difficult as the numbers involved are larger, and some of the more difficult ideas in the topic are tested. Reference page numbers haven’t been included in the margin, in order to make students who reach this level more skillful in researching through the chapter for their own information.
Easier Questions: These questions given in level 1 (sometimes also in level 2) are intended to build up confidence. Most of the questions are almost identical to the examples given throughout the chapter – except with the numbers changed. Reference page numbers are given.
Average Questions: The questions in Level 2 and Level 3 are of average difficulty level, and will give all students (weak, average & gifted) a good opportunity to practice and consolidate the ideas and rules given throughout most of the chapter. All students should try to complete and understand the questions in the first 3 levels. Reference page numbers are given.
