Final Exam Study Guide
The final exam will be on Monday, 1 May 2017, from 10:20 AM to 12:05 PM in Founders Hall room 2168. Everything in lecture & readings from the beginning of the structural geology topic to the end of the course will be fair game for test questions. The test will be a mixture of multiple choice questions, true-or-false, short answer, and fill-in-the-blank. I will also ask repeat questions from Test # 1 and Test # 2 (use your answer sheets to learn from any mistakes you made) - I may rephrase old questions (or not) & I may rearrange multiple choice answers (or not). But no new questions about old topics. Any geologic time scale question (new or old) is also fair game for test questions.
PLEASE BE SURE TO DO THE ONLINE STUDENT EVALUATIONS FOR THIS COURSE (= EARTH SCIENCES 1100) SOME TIME BEFORE FINAL EXAMS.
<<IF YOU NEED TO TAKE THE TEST IN THE TESTING CENTER (HOPEWELL HALL ROOM 88), YOU NEED TO TELL ME, OTHERWISE IT WON’T HAPPEN & THE PAPERWORK WON'T GET DONE>>
