Installation of Scilab is easy and it was installed correctly so we did not had any problem for that session. Some of the participants were did very well. Scilab is basically for numerical computations and many toolboxes are available in scilab. Ideal for Engineering students.
At the time of SAGE, found that on many machines either it was not installed completely or taking lot of time to get open as installed on virtual box.
I wanted to start the session. I checked on online sagemath.org site. Since college had good internet speed, we started to work on online sage.
Around 40 participants worked at a time and we had the session on SAGE with out problem for 2 hours. Thanks to SAGE online service. http://www.sagenb.org/
