Taking a break…

For each of the past 90+ days, in addition to teaching a full course load, I’ve posted a calculus problem and the corresponding solution.  Some of those problems even had video solutions available.  All of this was done to help prepare those who are taking the AP exam today, but I’ve found many who are interested in the calculus, but not taking the exam.

I’ve decided to take a break from posting daily problems and might resume at the beginning of the academic year, but I’m developing something that I think is really special for the upcoming year.

I’ll share it once it’s been fully developed.  Thanks for all of your support and interest in Calculus!  I look forward to connecting in the future.

Good luck on your exams!


My apologies…the solution to the problem of the day from March 24th was incorrect!  The correct answer is below and the post has been revised.  Thank you Andrew R. for letting me know this needed to be corrected.

Get Connected!


The past week has seen some significant accomplishments.  We’re fully up on Facebook and Instagram as well as launching this Website.   The primary goal is to help students prepare for the AP* Calculus exams by providing daily opportunities to review.


I intend to post on social media at most three times a day until the AP exam.  A problem of the day (POTD) will be posted each morning around 6 am (EST), and its solution in the evening around 6 pm (EST).  Some days will have a third post with a message from me that could arrive at any time.  Beyond those three posts, I may publish additional content to the website, which you would only become aware of by subscribing to the site (upper right-hand corner of site page).  Once the exam date has passed (May 9th, 2017), the POTD posts will stop, but I intend to keep the community going until exam grades are received.


My hope is that a vibrant and supportive community would form here and that you would find the site beneficial enough to spread the word to your classmates and those in upcoming Calculus classes.

Thank you for letting me be part of your journey, and I wish you the best in pursuit of your five!

Study Guides

One of the best ways to improve your exam score is to purchase a study guide for your exam.  In this post, I’ve provided links to several that are good options.  You’ll most likely only use the guide for the practice exams, so I would opt for more exams as long as the guide is rated highly.  I’m ordering each of these today.  I plan to offer video solutions to questions you have from specific review books.
