| Am soon to be taking my first MCP exam (210) and have heard a lot about new "Adaptive Testing", could anyone fill me in on what this involves, or is it just a posh way of saying "Multiple choice"
cheers | |

| The 210 has not gone to an adaptive format.
An adaptive exam uses a statistical process of discovery. It first presents a question of moderate difficulty. When the examinee responds, the question is scored immediately. If correct, the test statistically reestimates the person's ability at a higher level. The exam delivery algorithm then finds and presents a question that matches that higher ability. If the first question is answered incorrectly, the opposite sequence occurs. After the examinee responds to the second question correctly, the test re-estimates the examinee's ability as higher still; if incorrect, it re-estimates the ability as lower. The exam delivery algorithm then searches for a third question to match the new ability estimate. This process continues with the test gradually targeting the examinee's ability level. The exam ends when either the accuracy of the examinee ability estimate reaches a statistically acceptable level or when the maximum number of items has been presented. | |

| Just to add something to the fun times explained above.. I believe that the questions are weighted (I know Comptia's adaptives are)
So this means that for the higher skill questions you get more points. Lower skill means less of course.
This makes adaptives really brutal on any mistakes because you have to answer a few more correctly to get the point values up again.
Make a nervous mistake on a 'lower skill' question (or even a manual error) and you can really get punished on those adaptives! | |

| the advantage of adaptive exams are that they are over quicker (a+ exams are typically completed in ten minutes or less).
there is a myth that if you deliberately fail your first two or three questions that the rest of the questions will be of lower difficulty and the exam easier to pass.
i found both of my a+ exams to be of similar difficulty and scored 1002 and 890 in core and o/s respectively. | |

| You are right about the 'deliberate-wrong answer' scheme / myth of adaptive exams lol, I considered that one myself at first.
It always sounds like it makes sense but if you think it through then you realise you will always want to answer as many correct as possible. Adaptive or not. | |

MS exams are not adaptive.
Comptia A+ is adaptive for example.
is MS was adaptive, was a nightmare because adaptive exams are smart ones.. if you fails a couple of answers about a specific theme, the exam can bombard you with this kind of questions and kill you!!!!!! | |

| The only adaptive exam that M$ have had that I know of, was NT4 Server in the Enterprise. My Q's started off hard, and just kept going.  |
