MATH 4321    INFORMATION SHEET FOR TEST 3    SPRING 2015

• Test 3 will be in class on Tues April 14; it will last 70 minutes and is worth 30% of your course grade.

• The relevant sections for the test are those covered on the homework through Section 33 inclusive. The homework for that material is posted online.

• I will have an office hour on Monday April 13 at 2:30-3:30 pm in my office (PKH 462). Also, see my website for my usual office hours and the GTA's office hours.

• You should learn definitions such as ring, subring, division ring, field, unit, zero divisor, integral domain, homomorphism, isomorphism, (left/right) ideal, maximal ideal, prime ideal, irreducible polynomial, extension field, vector space, algebraic/transcendental element. 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 a (left/right) ideal. Moreover, any question in the homework or from the Quiz or from Tests 1 or 2 is game for the test. Work through all previous tests from this class; see the homework website for the links.

• No calculators are allowed; no notes are allowed; no phones, no tablets. You will need to put your belongings (including cell phones and tablets) by the side walls and possibly move seats in order to spread out in the room (if there are enough chairs & tables) - noncompliance will result in a score of 0 on the test.

• Bring some form of photo ID.

• It is your responsibility to be on time.

• 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.

• I plan to return the graded test to you on Thurs April 16 or Tues April 21 and discuss the solutions at that time.
