Anyone knows the formula inside the Bartle Test of players taxonomy?

I need to do the test, but I need the weight of each question to make something more accurate and trustworthy to the real test...

Some links to the online test:

    \$\begingroup\$ I wouldn't take the Bartle taxonomy that serious. There is a bit of each of the four types in every player. Which role they prefer depends on the game and on their current mood. You should rather see it as a simplified mental model to better understand player motivation. \$\endgroup\$

Erwin Andreasen, the co-author of the widely-taken questionnaire, links to the original question set (which seems to be the same one used on the sites you linked). Since the download link is somewhat hidden in an auto-redirect page, I'll just reproduce it in full here:

When playing a video game, is it more fun to:
+A Have the highest score on the list?
+K Beat your best friend one-on-one?

As you can see, there are no weights - each question has equal value, and simply chooses between two quadrants. Add up all the quadrants to get your final score.

Keep in mind that this questionnaire, and the taxonomy itself, is very simplistic and not rigorous at all. There are more accurate models for player psychology available. But as a simple way to understand that there can be different player motivations, this model is fine.

    \$\begingroup\$ Just to know about, what are these more accurate models? Can you list (maybe link) them? \$\endgroup\$

There is no real "formula".

The original presentation of a "Bartle Test" (as formulated by Erwin Andreasen) is to present the test-taker with a series of situations, and ask them to choose between two options, where each of the two options represents one of the types in Richard Bartle's Bartle Taxonomy of Player Types.

All you do to interpret the test is to add up the number of times the answer for each 'type' was selected. That's really all there is to it. There's no formula, no science, and there's no 'more accurate' or 'trustworthy' to be striven for. It's just a simple pop-culture personality test which gets you to say what you prefer to do, and then parrots back that you seem to be a person who prefers to do the things that you just said you prefer to do. Ooo, science-y.

The original question data, with the intended scoring for each answer, are available from the website of the test's creator, here. (it's the link labelled "original English question data set")

N.B.: In the original question set (which is used verbatim in both of the links posted in the question), 'Socialiser' and 'Killer' are each available 20 times, while 'Achiever' and 'Explorer' are each only available 19 times. This biases test results slightly towards producing higher 'Socialiser' and 'Killer' values. This may give you a hint at the lofty heights of scientific rigour under which this personality test was devised.
