Test One

Here are the solutions for the original first test and also solutions for the version for late sitters.

See the blackboard announcement sent out on Oct 1st for more details, email Steve (and Pete if you wish) if you have any queries.

Short description, head to blackboard on the day to do the test. Details appear there as well.

The test is on the first Monday back after the break (August 31), your 24hr-window of opportunity is Mon 10am to Tue 10am. You'll head to blackboard and then to the test information section

On the day, you'll see an honour declaration. Click the button to indicate you understand and will follow these guidelines, then the test will appear and your 2hr time-limit begins.

You have 2hrs in which to download the test, write up your answers, and finally submit your completed test. It is expected to take you around 90min to do the actual test.

If you have any problems on the day, I'll be promptly checking emails at certain times (Mon 10-4pm & 6-10pm, Tue 8-10am). You can email me your test if you have any problems.

Test Two

Test 2 will be accessed from Blackboard. Please go to Test Information on Blackboard to access the test.

Test two will cover three sections in the course notes: discrete random variables, continuous random variables and estimation. This week in the lectures I am going over the types of questions that often come up and examples. On Monday (October 5) I did the discrete section. Wednesday (October 7) I will do continuous. Thursday October 8 I will do estimation.

The test is on Monday October 12. As in Test 1, you have 2 hours to complete and submit the test. You can do this anytime in a 24 hour window beginning at 10am on Monday October 12. Once you have opened the test, you must submit within 2 hours.

Here are three previous exams (only the relevant parts for Test 2 are shown). This is more revision material for Test 2.

Blackboard tests

A practice test will appear on blackboard (via the left-hand menu link or otherwise) closer to test in week 13.


There is no textbook for Engr 123.

Detailed lecture notes will also be posted on the course homepages from week to week.

Assessment information

See the course outline for an overview.

To expand on the official assessment notes in the Course Outline, here is how your percentage mark is calculated, on which your final grade is based:

Assignments 25%, Labs 25%, Take-home tests 20% each, final blackboard test 10%.

There are two blackboard tests, you will choose one and that will count for the final 10% of your overall mark.
