IPS2 Diagnostic Exam Transfer Exam

Introduction Students come into the IPS program from all parts of the world, at all levels of English, as well as at various levels of mathematics proficiency. Rather than picking any countrys standard of math at this grade level, the IPS Mathematics department has decided to test on the content taught in the IPS program before the date of the entrance exam. That content is outlined below.

In addition, examinees are responsible for interpreting mathematical symbols and units where notation and measurements may be different from standards students are used to. Some examples of different issues students may encounter include:

Comma usage, or their absence, for large numbers (e.g., 1 000 000 = 1000000 = 1,000,000) Period usage and leading zeroes for decimals (e.g., 0.01 = .01 = 1

100 )

Imperial and metric units and their abbreviations (inches becomes in, centimeters becomes cm, etc). Understanding the units will not affect whether the student can answer the problem (see example 4 below).
