You test contains a section towards the end called Error Analysis. What this requires you to do is fairly simple. You must:
1 - Identify the incorrect statements in the letter
2 - Highlight the incorrect statement (Mr. Sgrignoli's class) or CIRCLE the incorrect statement (Mr. Lawhead's class)
3 - Correct the incorrect statement on the back of the sheet
Yep, it is that easy! There are 19 mistakes in the letter but you only need to identify 10. Good luck!
