Princeton REVIEW CAT??????????? [#permalink] New post   17 Mar 2007, 13:28
My tutor said it was adaptive and the scoring system was right. I got 4 wrong on the math and that was a 45. I got 4 wrong on the next test and that was a 44. All the problems were hard and in the middle. THis system can't seem right

were the four you got wrong in early in the section? were they in bunches? the fact that they are adaptive explains why you got two different raw scores...

I think your assumption here is that the hard questions in the middle of the exam were of the same difficulty level which might not be true. Computer-adaptive test gives you harder questions as long as you answer the previous questions correctly. The level of difficulty goes down when you answer the questions wrong. The tests zeroes in on your approximate level. That's why it's almost impossible to get a score of 700 5 times. More likely the scores will be something in the range of 680-720.

Answers wrong: 5, 16, 23, 32. I knew all were hard. There is no way this should be a 44

I still don't understand your reasoning... You could have 50% of the questions wrong and still get a 45. It depends on the level of questions you are getting.

The questions were all hard. I guarantee that. And its impossible to get 4 wrong and get a 44

Why don't you try MGMAT's CATs then? Their algorithm is better than Princeton's...

I suggest you try GMATPrep. I too found PR CAT math to be kinda weird..the problems were easier than those in GMATPrep yet it's harder to score better than GMATPrep... :?

I have taken every GMAT prep, Manhatten. I usually score 47-50 on everything. I was just wondering because my Princetonreview tutor told me the math is perfectly adaptive. He has no reason to lie because I have purchased everything. Getting 4 wrong twice shouldn't equal a 44 and 45 even without getting easy wrong. Also, I got the first like 8 right.

This is my take on PR CAT:

The final raw score is a good predictor of where you are. The number correct/incorrect is not. The PR CAT math is easy, but punishes incorrect answers.

Is that you in the picture? It looks like Dave Chappelle. Anyways, reading the other posts, people have stated a couple of things. Alot of people have mentioned problems with the scoring PR system. Other people mentioned that its a myth the first 10 questions mean more. You really think 4 wrong could lead to a 44? Even if you got the 4 easiest question wrong, and they were in a row?

PR CAT [#permalink] New post   20 Mar 2007, 00:38
Hey,ys

I finished the PR course a month ago. The class manual is a good intro, and I believe that the course approximates the Manhattan Review. My next stop.

I was just going to mention that My instructor, good friend, always asserted that those PR CATS are actually programmed to focus on the presentation of course material. Infact, the CATS actually weight material based on the attrition of the class. Thus, the major discrepancy in test results.

If you want a true estimate, you'd probabley be better off with something other than PR CATs. I feel I know PR backward and forward. Let me know if you have any other concerns.

Now that I think about it, Dave Chappelle did a spoof of Antwone Fisher. Derek Luke played Antwone Fisher in the actual movie.

The purpose of practise tests is to see how good you can do for the real GMAT and their scores can only be an approximate estimate for your true GMAT score. Some estimates may be better than others. Don't focus on how good their scoring mechanism is. It does not matter.
