Patrick,

There are many examinations (in India), for higher education like the Common Admission Test for Management Courses, and for employment like the Civil Services/Banks/Insurance Companies etc. with Basic Mathematics as one of the subjects. I had earlier prepared these questions papers for my students. Most of the questions are objective type with four answers given to choose from. However, I don't give the options here. These questions are all to be answered within a minute, some within half-a-minute.

I add to my collection of books, and the Question Bank as a result. Often, I make some changes in the questions . Sometimes I put my own questions. I also get them from Senior School/Pre-University question papers.
