One more thing. Just one advice for your check, not just relating to this question in paticular. Bear in mind that no checkers knows
everything. Just look how different answers you get on this question. (30 deg, 90 deg, whatever you like, can't do it from that holding at all!)
Hence, if the checker is the stubborn and nit-picking type (that at the same time is not aware of the above paragraph), you may do it one way or the other and he will say what you are doing is wrong anyway.
Beware of this kind of personality type. In this case, just have a good explanation ready for what you did if it will ever become an issue. If you show that you thought about what you were doing you might save the check anyway (even if you did it the right way, and he doesn't agree). Big discussions and hitting the checker in the head with the books is not the way forward in a hiring situation. Even if you are right, perhaps he'll get annoyed and fail you on some other mistake that you did, or tell that you have a bad personality.
No normal thinking checker would fail you for turning left or right out of that holding anyway. He is probably more interested in seeing that you are able to make the correct entry. In fact he would probably give you a vector when he feel that he have seen enough holding stuff.
Be consistent, do the same every time. In the unlikely event that you have to exit that holding twice (or any other situation where you are in doubt), do it the same way both times. It's easy to teach you to do something different once you get the job. But if you do thing differently with each maneuver it make you appear that you are uncertain of what you are actually doing.
