Dear experts,

Can someone please recommend me some good links where I can learn good strategies to tackle mixture solving problems?

It has been so challenging for me those kinds of problems, I know that they can be solved with allegation method and weight averages but a lot of them require more than that.

In your opinion, how can I improve on that topic?

Thank you so much in advance and happy new year!

Here's our video on mixture questions:


It's important to note that we can often use Weighted Averages to solve mixture questions:

Hello Bunuel!

I've already read all those links, very helpful btw. But when I go and try to solve PS questions in the forum I found that a lot of problems can't be solved with weighted averages.

Is there another form to solve mixture questions?

Regards!

Hi jfranciscocuencag,

To start, "mixture" questions are a relatively rare category on the GMAT - you'll likely see just one mixture question on Test Day - so you shouldn't necessarily put a lot of effort into this one question type. By extension, unless you're already doing really well on the major categories in the Quant section (such as Number Properties, Algebra, DS overall, etc.), you're probably leaving a lot of points behind that have nothing to do with mixtures. That having been said, many mixture questions are ultimately just 'math' questions (although in certain variations, you can occasionally you can use a Tactic such as TESTing VALUES or TESTing THE ANSWERS), so if you are comfortable doing Algebra then you can train to handle just about any mixture question.

1) What study materials have you used so far?
2) How have you scored on EACH of your CATs (including the Quant and Verbal Scaled Scores for EACH)?
3) What is your goal score?
4) When are you planning to take the GMAT?

GMAT assassins aren't born, they're made,
Rich

Hello Rich!

I didn't know they were rare in GMAT.

1) I attend one person to person prep course.
2) I have never taken the CAT, it's not very usual here in Mexico. (I guess you are referring to the CAT's exam, right?)
3) +680 GMAT
4) Before November.

Thank you so much!

Hi jfranciscocuencag,

Taking practice CATs/mock exams - at regular intervals throughout your studies - is an important part of properly training to face the Official GMAT. Since it sounds as though you have not taken any yet, then it would be a good idea to take a FULL-LENGTH practice CAT Test; you can take 2 for free at www.mba.com (and they come with some additional practice materials). Once you have taken that first CAT, you should report back here and we can discuss the results.

Hi jfranciscocuencag,

To help me provide some specific advice, could you post a mixture problem with which you are struggling? I’d be happy to provide a solution.
