Student Name Biology Form 401 Spring 2004 Released Test Booklet Page 2 Page 3 BIOLOGY 41401 3 Go On SECTION I Directions: Today you will be taking the Biology End-of-Course Test. Read each question carefully and then choose the best answer. Be sure that the question number on the answer sheet matches the number on the test. Then mark your answer by filling in the circle on your answer sheet. Do not write your answers in the test booklet. If you do not know the answer to a question, skip it and go on. You may return to it later if time permits. If you need to change an answer on your answer sheet, be sure to erase your first mark completely. Do not make any stray marks on the answer sheet. If you finish the section of the test early, you may review your answers in that section only. You may not go on to the next section or return to a previous section. The two practice test questions below are provided to show you what the questions in the test are like. For each question, you should choose the one best answer and fill in the circle in the space provided on your answer sheet.
