Amazon.com description: Product Description: This study guide targets teacher competencies and skills for Biology. You read four years worth of material between the covers of one study guide. Regardless if your test is multiple choice or essay format you will have ample material to reflect upon to do well on these formats. The majority of XAM study guides have 125 question multiple choice sample tests. The questions are medium to hard in difficulty but reasonable for a trained teacher candidate to answer. Since the questions do highly resemble the real test we are frequently asked if they are former tests. They are not. If any question from our book appears on the test it would be a coincidence. XAM Publishing, Inc. has e-mail support at winwin1111@aol.com. XAM staff welcomes your updates and values your input. Each year a new version of the study guide is released so you may have the best in educational research.
