Unformatted text preview: 4. ' Bio}. 210 Last Name (print) First Name (print) Lab Section # (write Lecture Only if not in a Lab) IMPORTANT! READ THESE INSTRUCTIONS! - Print your name and section number in the spaces above and on your Scantron answer sheet. - If you can’t remember your section if, write the TA's name and lab day and time in the space above. 0 When the test starts, bubble your answers on the Scantron form carefully and accurately. One point is the reward for a perfectly filled out Scantron. - Please read each question and all choices carefully before answering. Each correct answer is worth 2 points. - You may write on the exam. - Make sure that you do NOT put any extraneous marks on the Scantron answer sheet especially in the area to the left that is needed to read the form. 0 Hand in the exam with the Scantron slipped into it. Picking up Exams and Scantrons The ONLY way to find out your score and grade is to pick up the exam and the Scantron at the beginning of the lecture from Dr. Hemmingsen. DO NOT advertise your absence from lecture by asking Dr. Hemmingsen outside of class for your grade either in person or by email. The Key to the exam and the grade distribution will be posted in the glass cabinet opposite LS-420. These materials will be removed when the Practice Final exam is posted. Do not ask the TAs or the lab coordinators (Mariene and Tom) for your exams or lecture grades. $32.9 @ 10.
