1. What about it? If you do not say what problem you are having, then how am I supposed to help you?
2. If you are referring to the BPP Study Text, then I do not have it – I only have their Revision Kit. (But if you are watching my free lectures then you do not really need a Study Text – the lectures are a complete free course and cover everything needed to be able to pass the exam well. It is the Revision Kit you need, because practice at exam standard questions is vital to being able to pass the exam.)
3. As far as calculating the learning rate, then watch my free lectures. I show how to calculate it, with examples.
If you are still unsure, then say exactly what your problem is and then I will help 🙂
