Models, 6e by Bittinger/Beecher/Ellenbogen/Penna.
There are six alternate forms for each chapter test and the final examination. Alternate
Forms A, B, C, and D are equivalent in length and difficulty. Synthesis questions occur
UV
at the end of the Form, and are separated from the rest of the questions by a solid line.
Synthesis questions are meant to be more challenging than the previous questions, like
those problems found in the last part of each exercise set in the text. The synthesis
questions have been placed at the end to make it easy to omit them if the instructor
wishes to do so.
IA
All questions on Forms E and F are multiple choice. Effort was made to make the
wrong answers as logically wrong as possible. In most cases answers were constructed
to avoid students doing backward reasoning.
