Yup, that is usually part of the test as well. Rather than try to find a certain tech to do for each attack, you should just try to react. Why do I say this?? You're going to be nervous enough without having to worry about a list of techs.
I've done tech. lines with students and have had them stand there looking at me with that 'deer in the headlights' look because they were unsure of a response for the attack that was thrown. I'll say to you what I say to them. You know who to move, block, punch, parry, and kick correct? In that case, do just that!!!! React!!! Now, I'm not sure if your Inst. is expecting a certain tech. from the curriculum, but usually at that portion of the test, they just want you to defend yourself. If a punch is coming, and you step, block, and kick...you defended yourself right???
Easier said than done, but just stay relaxed. Like I said before, if you were not ready I dont think that you'd be on the test!Mike
