This book contains questions taken from the O Level Additional Mathematics papers that have been randomised. That means each time the new problem button is clicked, a similar problem is presented but with different values, orientation, angles and/or dimensions. No detailed workings are given for the solutions, only the final answers. Since these are randomised versions of essentially the same problems, the detailed workings to find the answers would be similar to those found in the 10-year series books published every year. Very often, graphs and figures are also given as part of the answers, even though they are not asked for, so as to give more insights to the problems for the students.
