Computer Aided Learning of Mathematics (CALM) has been in use for some time in the Prep-Year Mathematics Program at King Fahd University of Petroleum & Minerals. Different kinds of software (both locally designed and imported) have been used in the quest of optimizing the recitation/problem session hour of the mathematics classes. This paper describes the software selection processes, and the in-classroom evaluation of the software. The attitude of teachers and students towards selected software was positive. A majority of the students believed that they had benefited from the software, and the software indeed "aided" them in learning mathematics. The teachers enjoyed generating quizzes and tests using Test Bank, and the students enjoyed the use of Online testing to do their quizzes. Based on the findings of this experiment, the software was recommended for adoption in all mathematics courses of the Prep-Year Mathematics Program.
