  MATH 4321             INFORMATION SHEET FOR TEST TWO           SPRING 2012


  * Test 2 will be in class on Thurs Feb 23. Test 2 will last 20 minutes.
  
  * The relevant sections for the test are Sections 18-24. The homework 
    for that material is posted online at my website 
    https://vancliff.utasites.cloud/T/S12/hwk4321.html . 
  
  * My office hours are Tues and Thurs 4:00-4:50 pm. In addition, some class 
    time before the test starts will be available for asking me questions.  
    Ph: 817-272-3932, e-mail: vancliff@uta.edu .
  
  * You should learn definitions such as ring, subring, division ring, field,
    unit, zero divisor, integral domain, homomorphism, isomorphism, field of
    quotients. You should be ready to present examples like those occurring 
    in the homework, and be able to show that a subset of a ring is a subring. 
    Moreover, any question in the homework is game for the test.
    
  * As part of your study, I suggest you look over all the homework problems
    and your solutions to them, skim through the lecture notes, and look over 
    Test 1 and its solutions; see  vancliff.utasites.cloud/T/S12/4321t1s.pdf
    for the solutions to Test 1 (use password  math4321  to open the file).

  * No calculators are allowed; no notes are allowed. Bring some form of 
    photo ID.
  
  * Try to keep your eyes on your own work during the test.
  
  * If you wish to leave the room during the test, you should ask permission 
    first & turn in your test to me. Only in exceptional circumstances will 
    I let you continue the test should you return. (So it is better to be 
    3 minutes late to the test, rather than ask to go to the bathroom during 
    the test.) If you finish early but prefer to stay in the room, then you 
    should NOT get out any work, book nor item, no matter what the subject 
    matter is, without first checking with me.  Should you wish to leave 
    the test early, then you may.
  
  * It is your responsibility to be on time.
  
  * I plan to return the graded test to you on Tues Feb 28 with a solution 
    sheet.
