mcat math without a calculator 1 tutorial videoWhile the pre-2015 MCAT only tests you on science and verbal, you are still required to perform complex mathematical calculations WITHOUT A CALCULATOR!

Unfortunately, studying the sciences alone won’t help you here as the math equations tend to trip up students in many ways:

  1. You may get stuck in knowing how to apply math to the required science question.
  2. Perhaps you know the required math but feel lost without your calculator.
  3. Even if you do know how to do the MCAT math without a calculator, you find yourself wasting too much precious time working through the calculations.

So as you prepare for your MCAT you should be focusing on learning the required math in addition to studying your sciences and practicing verbal passages.

The key to a successful math strategy involves:

  1. Learning how to do the required math without a calculator
  2. Learning the correct tricks and shortcuts to get through these questions QUICKLY AND EFFICIENTLY

  4. Hey Leah!

    Thank you so much for these video series, it’s a HUGE help especially for someone like me who depends on calculators. Just a quick question, if I am multiplying two decimal numbers and I round one up but the other down, how should guesstimate my answer would be? You mentioned if both numbers are rounded up then your actual answer should be less… so what if one is up and the other is down?

    Thank you once again for all you amazing help 🙂

      You’re very welcome Nabeel. Guestimate closer to compensate for the one that was rounded MORE. Meaning, if you round 1.01 down to 1 and 2.69 up to 3, you should estimate taking 2.69 into account more than 1.01 since the smaller rounding won’t change the value as drastically
