Tips for the CELS test.
Here's last years feedback for the terms test:

With multichoice, when they say the BEST answer, then the answer they want is the only one that can be DIRECTLY concluded from the opening statement in the question. In that feedback file they go through that question on the secreting cell. B is the ONLY answer that follows DIRECTLY from "a cell that is secreting proteins". The other answers require assumptions. Other than that the multichoice section should be easy.
With the short answers, be as succint as possible no matter what. Write very short sentences that get the point across with minimal words. Never ever ever try and waffle. It's fine to put down some points that may not directly be answering the question, but put them at the end and do not spend much time on them. Sentences should be less than a line long on the page preferably. Make sure you answer the questions too. Think carefully about what they want you to write down, not what you think you know about that question. In our MSO meetups alot of the time you guys would offer words that were related but it didn't answer my question at all when I asked you. Write what the examiner wants to hear, not what you think you know about that subject.
