Solutions will not generally available through the web. You need a cise account and directory access. This precaution is being taken by instructors everywhere, to prevent easy access to solutions by students at other universities. The /cise/class directories are provided by our department for precisely this purpose. All previous numerical computing instructors have used this facility (as opposed to the web) for posting solutions.
SAMPLE MIDTERM solutions are posted in /cise/class/cot4501fa00/SOLUTIONS/SAMPLE-MIDTERM. Make sure to read the README file in this directory.
