GMAT Tuesdays with Kevin: Percent Change Trap

Beware of this common percent change trap! Keep this crucial concept in mind to help you stay safe on the test: if you go up by a percent and down by the same percent, you won’t end up in the same place. Also, make sure to come back next week, and I’ll teach you how to solve this problem faster :).

Let us know if you’re having any difficulties with GMAT percents in the comments below, and we’ll be happy to help!

    Hi Kevin, thanks a lot for help. I would appreciate if you give more classes on problems or mistakes related to percentage or percent change :) I am a distressed damsel :( Please help with more videos and tutorials.

      Hi Sid! Thanks for writing in! :) I am always stoked to hear from students who watch GMAT Tuesdays.

      I’d be happy to do more videos on percent change and percentages! :) They can be tricky problems for sure. And I don’t want you to be distressed!

      We just recorded a chunk of videos, so I won’t record new ones for about a month. When I do, I will definitely include one on percentages! :)

      Have a stellar day!

    Hello Kevin,

    I like the style of your teaching – it makes the learning entertaining and fun :)

    It would be good to have the question text on a static computer screen or as a text in the post itself, to follow better.

      Hi Sonia! Glad to hear that you like the videos. :) I try to make them as fun as possible since I know studying for the GMAT is not always fun. I really like your suggestion about having questions in the text of the blog post. I think that would definitely help students. When I work on a problem, I’ll make sure to do that from now on. Happy studying! :)
