Biology Keystone Study Guide

Introduction

  • Designed to help students prepare for the Biology Keystone Exam (BKE).
  • Provides information about the exam, tips, and strategies for preparation.
  • Keystone Exams assess proficiency in subjects like Algebra I, Literature, and Biology.
  • Part of Pennsylvania's high school graduation requirements.
  • PDE works to align curriculum, instruction, and assessment practices through tools like the Assessment Anchors.

How to Use the Study Guide

  • Organized into three sections: Overview, Preparing for the BKE, and Test Content.
  • Overview explains test dates, time, and format.
  • Preparing section offers study skills and test-taking strategies.
  • Test Content section details what the exam measures and includes practice questions.
  • Materials needed: study guide, pen/pencil, paper, highlighter, dictionary, biology textbook, teacher.

Overview of the Biology Keystone Exam

  • Administered in spring, summer, and winter.
  • Two modules: each has 24 multiple-choice and 3 constructed-response questions.
  • Required for graduation but does not affect the final grade.

Preparing for the BKE

Study Skills

  • Time management, organization, and active participation are crucial.
  • Realistic goals, study during productive times, and review previous material.
  • Avoid marathon study sessions and take breaks.

Test-taking Strategies

  • Understand the test format and practice with sample questions.
  • Use positive self-talk and mark key ideas in your test booklet.
  • Read all questions and choices carefully before answering.
