MATH 4321    INFORMATION SHEET FOR TEST 3    SPRING 2014

• Test 3 will be in class on Tues April 8; it will last 50 minutes and is worth 30% of your course grade.

• The relevant sections for Test 3 are Sections 18-24, 26-27, 29-31, 33 only. The homework for that material is posted online.

• My office hours are Tues and Thurs 3:30-4:10 pm and the GTA's office hours are given on my course website. In addition, some class time before the test starts will be available for asking me questions.

• You should learn definitions such as ring, subring, division ring, field, unit, zero divisor, integral domain, homomorphism, isomorphism, left/right ideal, ideal, etc. 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 or left/right ideal. Moreover, any question in the homework or the Quiz or Tests 1 & 2 is game for the test. I recommend you look over the Quiz and Tests 1 & 2; the solutions to those are posted at my website.

• No calculators are allowed; no notes are allowed; no phones, no tablets.

• Bring some form of photo ID.

• Try to keep your eyes on your own work during Test 3.

• 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 hope to return the graded test to you on Thurs April 10 (or Tues April 15 at the latest) and discuss the solutions at that time.
