How to use these Year 13 binomial expansion for rational n and series modelling multiple choice questions
First, read each question carefully before you look at the four answers. Then work the answer out on paper, so that you do not simply guess. After that, read the explanation, even when you are right. If you score less than 7 out of 10, go back to the binomial expansion for rational n and series modelling lesson.
Finally, practise more with the binomial expansion for rational n and series modelling worksheet and the quiz. Moreover, all the pages of this chapter work together, so you can move between them at any time. For example, many pupils read the lesson on Monday, practise on Wednesday and test themselves on Friday.
