BPP Study Text & BPP Practice Kit references

Hi
I quite pleased with the progress I’m making towards studying for the exam. However, there are some references that a in the text book especially the Study Text they just don’t make sense to me.

First: Let’s take chapter 4 (Limiting Factors) from the BPP study text, just below there is a topic list and syllabus reference, under topic list you will see 1. Limiting Factor and next to it under syllabus reference is B3 (a). I’ve been trying to refer to this B3 (a) with no success.

Secondly: At the very last page of the chapter right at the bottom you have “now try the below from the Practice Question Bank” (Number (Q2), Type (Section C), Marks (20), Time (39 mins)). I don’t know how to follow the references stated below. What does Q2 refer to? Is it question 2 of the practice kit for 20 marks? If I refer to the practice kit it’s something different from what I studied in the chapter. Some chapters will be referenced Q6-10 etc.

Can someone assist with the two points I mentioned, using the very same examples above and where can I find these references (If you can tell me which page numbers they are referenced to it will be helpful so that I can apply it to the other chapters)

Thank you
