Let me walk you through how it's laid out — Page 176, Lesson 162

This is the answer key for the specimen examination paper. Let me walk you through how it's laid out. Across the top, you see question numbers 1 through 12, and directly below each number is the correct answer letter — C, a, b, a, b, a, a, C, a, C, b. Below each answer, you'll see a weighting marked as "W1" or "W2". That "w" stands for the marks allocated to that question. So question 1 is worth 1 mark, question 12 is worth 2 marks. Moving down, questions 13 through 24 follow the same pattern. Question 13 answer is C, weight W1; question 14 is C, W1; 15 is a, W1; 16 is p, W2; 17 is d, W1; 18 is C, W1; 19 is a, W1; 20 is a, W1; 21 is b, W2; 22 is a, W2; 23 is d, W1; and 24 is C, W3 — that's a 3-mark question. Then questions 25 through 36: 25 is C, W2; 26 is d, W1; 27 is b, W1; 28 is p, W1; 29 is a, W1; 30 is p, W1; 31 is b, W2; 32 is b, W1; 33 is d, W1; 34 is b, W1; 35 is a, W1; 36 is C, W1. Questions 37 through 48: 37 is d, W1; 38 is b, W1; 39 is C, W1; 40 is p, W1; 41 is a, W1; 42 is a, W2; 43 is b, W1; 44 is d, W1; 45 is b, W1; 46 is p, W2; 47 is blank with W1; 48 is blank with W2. Finally, questions 49 through 55: 49 is b, W1; 50 is C, W1; 51 is d, W1; 52 is p, W1; 53 is b, W1; 54 is blank with W1; 55 is blank with W1. You'll notice some answers show a lowercase "p" — that's the answer letter for those questions. Some entries are blank, meaning no answer is listed for that question in this key. The page number at the bottom is 644. These are the book's practice questions — let's try them one at a time.
