CS106X Handout 28 Winter 2008 February 13, 2008 CS106X Practice Midterm Exam Facts: When: Tuesday, February 19 th at 7:00 p.m. Where: Gates B01 Coverage The midterm will test everything up through this past Monday’s lecture on pointers and arrays (but no linked lists), though the exam will emphasize material exercised by the three large assignments. We will not be especially picky about syntax or other conceptually shallow ideas. We are looking for a clear understanding of the core programming concepts in C++. The exam is open-book and open-notes, but no computers allowed. Don't let the open- book nature mislead you. There is not enough time to learn or re-learn the material during a three-hour window. You should be experienced enough with the material to readily answer the questions, relying on your notes only for the occasional detail. Writing code on paper in a relatively short time period is not quite the same as working with the compiler and a keyboard. I recommend that you practice until you are comfortable handwriting solutions in to small problems starting from a blank sheet of paper. You won't have to look far to find lots of practice problems (this handout, section handouts, textbook exercises, lecture examples, etc.). SCPD students can either come to campus, or they can take the exam remotely anytime after Tuesday night at 7:00 p.m. The exam will be posted as a handout once it’s been administered, at which point you can pull it, print it, give yourself an uninterrupted block of three hours to take it, and then fax it in to me when you’re done. My cell and fax numbers will be printed on the front page of the exam. You can call me during if you have questions, and you can use the fax number to get us a copy of your exam. Hold on to your original until you get the faxed copy back. You don’t need to take the exam at the office, and you don’t need a proctor. Just self-administer so you have maximum flexibility on when you take the exam. Note: This exam is slightly longer than you’ll see on Tuesday night. I thought it was more important to put as many examples on the practice midterm as possible.
