  • I think in the video where you are rephrasing one of the geometry question there is an error in that rephrasing.

    You said is x = 90*

    Then your further rephrased that as Is AB diameter of Circle but it should be rephrased is AC diameter of Circle? As anyone can tell without looking at figure that AB can't be the diameter of circle.

    Printing error.

    • Thanks for catching that, Komal!
      We have now fixed the video and uploaded it.

      Thanks again,

  • Excellent video. Thanks Brent.

  • Anyhow Brent Hanneson this is a excellent video and I'm looking forward for some more videos on similar lines.

    Do you have any plans for similar videos on PS, SC or CR section? Please do upload some videos on all the sections.

    I'm loving it :)

    • Thanks for that feedback, Komal. I'm really happy to hear that you're enjoying this series!

      The entire Beat The GMAT team and I have been really pleased by our community's response to these videos, and we're thinking that it may be a good idea to create videos on possibly other sections or subjects.

      Are there any particular subject areas (e.g., geometry) that you think would be good for us to address in a similar series?

  • Can you do a video on Picking Numbers in Quant DS.

    There's a good post on the forums that looks like a useful topic to explain via a video
    see "Today's topic: Picking Numbers in Quant " since its an important strategy

    • A video on Choosing numbers in DS is coming out on Tuesday :-)

      All the best,

  • Yes Brent Hanneson, I would love if you can add video on CR boldface and fill in the blank questions in CR. These 2 question type are my headache. :(

    Also, it would be great to see some lessons on RC and SC.

    Thank you again for all the help and great videos.
