Shoto, I just talked to one of the research directors and one the psychomatricians here at my work (we don't develop or score the CLEP) but I tried to nail them both down to a minimum number one would have to get correct given the variables we do know. I had no luck.

When you think about it, it kinda makes sense too. All the basic advice is correct, focus on answering what you definintely know, don't spend valuable time on something you know you can't figure out... This is because there's no penalty for guessing and you've got a 20% chance of getting it right so not answering an item can be more detrimental than guessing.

As for the field test items (CLEP calls them pretest), there is ABSOLUTELY no way of knowing which is which. If you gamble and assume, you may be wrong. This I can say for sure - treat each item as if it were live and counts toward your score. Don't fall into the trap of allowing "throw away" questions. CLEP doesn't even tell you how many field test items there are so you would be totally shooting in the dark to guess.

Good luck!
