<p>Hi,</p>
<p>I did two FR sections on the CB website, and my total score for that section was about 30 out of 54.
Why are FR questions ridiculously hard?
Are there any tips on doing well on them?</p>
<p>Thanks.</p>
<p>You can save time by leaving expressions in unsimplified forms. For example, you can leave 1/2 + 1/3 + 1/4 + 1/5 as your final answer without showing any more work. I suggest you to take the 2006, 2005 2004, etc... free response questions for practice. Another hint, know the types of questions that will be asked. I am 99.99% sure that you will see:</p>
<p>-One problem involving areas, solids or revolution, cross-sections
-One problem involving parametrics, finding speed, length of curve, etc...
-One seq and series problem in the no calculator section (yea with Lagrange Bound error)
-One problem where they give you some chart and they ask you to do some approximation (using trap rule or something like that) [50% of the time you will see this]</p>
<p>From all the released free response questions, polar areas seem fairly rare. But still know the formulas just in case.</p>
<p>Yatta!: Thanks for your advice. :)</p>
<p>Also, I found that you can sometimes "reuse" integrals on the calculator part.
i.e. the integral you use in part a of a question will be very similar to the integral used in part b, so just copy and paste the integral from part a and change whatever needs to be changed instead of typing it in from scratch every single time</p>
<p>I think if you know what you are doing, then you will have plenty of time left over after frq's.</p>
<p>I don't feel much time pressure on FR questions. Rather, I often run of time on MC.</p>
<p>Just read VERY CAREFULLY. I find most of my errors are due to foolish mistakes.</p>
