† Dr. Radhakrishnan was not aware of the cost of the package.

I had reviewed the above-mentioned CAL package recently and I am impressed with this package. I particularly enjoyed viewing the "live" illustrations, which I believe will be very useful to our students as we are able to demonstrate most of the techniques here.This package also allows the users to choose what they want to learn. For example, newcomers to this subject will need to familiarise themselves with new terminology and this programme has that capacity. Those with some previous knowledge can choose to not read the explanationfor terms that they are familiar with.The little question and answer sessions in the coursematerial allow the students to think while they are using the package.I might like to suggest that you include more of these question and answer sessions in your package. Overall, I would like to say well done.
