Need Explanation on LPI Scoring System

Hello guys, just passed my LPI 101 exam last week with a score of 630 (don’t know how they arrive at this mark). Here’s the breakdown:

Section Analysis Number of Questions Number Correct Percentage
Hardware & Architecture 7 5 71%
LinuxInstallation/PackageManagement 14 14 100%
GNU & Unix Commands 20 19 95%
Devices, Filesystems & FHS 16 12 75%
X Window System 8 6 75%

FHS – Filesystem Hierarchy Standard

Most certification sites say the exam is 50 questions but the exam is actually 65 questions (Your best bet is to get any information you need from the lpi.org site itself)

Some of the questions been asked from these practice sites are also based on LPI 102 objectives so is better you do your reading & preparation based on LPI 101 detailed objectives.

You can be assured that no questions will asked outside their detailed objectives. If you study & practice all the topics, key terms & utilities passing will not be a problem.

P.S: Can anyone please explain how the scores are been calculated because considering the fact that I got 56 over 65 that will give 86.2% but the score of 630 over 800 will give 79% what makes it more confusing is that the average of (71%, 100%, 95%, 75%, 75% gives 83%).

Please I need explanation so that I know how to prepare effectively for my LPI 102

I can't shed much light on the cryptic marking scheme of the exam but if you read throught the info on their website you'll see that different questions are weighted differently - based on either importance or difficulty or both I suppose.

That means that if you answer A right but get B wrong you might not get 50% because A might have a higher rating like 62%.

Also, just to make it even more fun, they sometimes include trial or beta questions which don't get counted.

So basically it's impossible to determine the percentages because they make em all screwy in the first place.

As for the 600, 700, 800 levels...my understanding is that with an adaptive, weighted test, the final score is determined by the questions answered correctly, their level of difficulty and the time taken to complete the test.

I might be wrong but to me that means that two guys could both get 80% but one might have 620 and the other might have 670 because the second guy answered the harder questions right.

That's what i've read and been told. I know it doesn't really answer your question and it could be inaccurate, but it's all I got.

I'd be interested in hearing any other replies too.
