No, I think he meant that he wants at least a 10 on the TFE section.
For CDP, I have realized that the line counting method works a lot, but this is not the case with the actual DAT. You can at most eliminate 1 answer and the rest have the same no. of lines. You can start with this method and then slowly once you get the hang of it, you could start visualizing the object. What works for me though is the distance of certain events (a circle or a box in the middle of the object) from the ends and whether you should be able to see it from that end. This wil help you narrow down when you are stuck between 2 options...
Don't know if this made any sense, but its very difficult to explain PAT by just writing it down...Just search TFE threads and you will find very good tips on how to get better at it. There are a lot of good explainations out there...
