Howard's office hours while he is lecturing will be the Mon/Wed workshops listed below.

David's (course coordinator) office hours are Monday/Wednesday/Friday, 11.30-12.30 in CO537 (Cotton building, south end). Or email david.cox@vuw.ac.nz

Howard is in charge of the labs, their supervision, report marking, and the lab content for this course. He will run in-person workshops every Monday and Wednesday from 5.30pm - 8.30pm in CO118 and CO119, starting in week 1.

Class Representatives and Facebook page

Thanks very much to our two class reps, Crystal D'Mello and Connor Hindle for volunteering! You are welcome to contact them directly by email. Crystal: dmellcrys@vuw.ac.nz and Connor: hindleconn@myvuw.ac.nz

You are also welcome to join the Facebook page they've set up for this class: https://www.facebook.com/groups/1630039470493431/


Here is the Discord channel for Engineering and Comp Sci. When you join you should go to the bot channel and type in

(exclamation mark)rank engr-121

and then you will have the maths role added, so you can access the 121 channel. You can also do this for your other courses.

Discord provides an alternative to Facebook for ENGR121 students to text or chat with other ENGR121 students.

Rainbow Discord

The VUW UniQ discord server is to be found at https://discord.gg/PyxnDu6 . UniQ is our rainbow representative group on campus. They provide social and support space for students, a critical service during this potentially isolating time.

Extra Help

The office hours of math and statistics academics will be listed here.

Math Help Desk

The Mathematics Help Desk is a good place to come and ask questions if you are having trouble understanding tutorial and/or assignment questions, or material covered in lectures or in your extended reading. You are welcome here any time.

Dr Howard Lukefahr will also run a Workshop for all ENGR students, see info under People above.

Lecture Notes

Assignments and Tutorials and Answers


Test One

Test One (25%) will be an online Blackboard Test on Thursday 10 September (week 7). You will be able to start the test any time on that day between 9am and 4pm. Once you begin, you will have 2 hours to complete the test. Each student will be on their honour to ensure that the answers submitted are entirely their own work, done without collaboration with any other person. Tutorials in week 7 will be a chance to revise, using a Sample Test 1, plus previous Tests.

Test Coverage: Test One will cover Howard's section of the course (weeks 1-6). Material in Assignments 1-4 is included, and material in the corresponding tutorials (up to 1 September).

Test One is worth 25% towards your final grade.

Our policy in ENGR121 on showing working in assignments, Tests, and the Exam, is that it is always a good idea to show working. Some questions will explicitly ask you to show working, and in that case you will need to show your working to get full marks. If working is not asked for, you can get full marks for a correct answer even if there is no working shown. An incorrect answer with no working shown cannot attract any marks; this is the danger of not showing your working.

This formula sheet will be provided with the test.

Examples of Test One

The best indication of what to expect in Test 1 will be the Sample Test 1 on Blackboard. We will let you know when it is available.

The following are not as good as Sample Test 1 on Blackboard, because they have more limited coverage, but are included here for your information:

Test Two

Test Two (25%) will also be an online Blackboard Test, on Thursday 15 October (week 12). You will be able to start the test any time on that day between 9am and 4pm. Once you begin, you will have 2 hours to complete the test. Each student will be on their honour to ensure that the answers submitted are entirely their own work, done without collaboration with any other person. Tutorials in week 12 will be a chance to revise, using a Sample Test 2, plus previous Tests.

Test Coverage: Test Two will cover Emma's and David's sections of the course (weeks 7-11). Material in Assignments 5-8 is included, and material in the corresponding tutorials (up to 6 October).

Test Two is worth 25% towards your final grade.

Examples of Test Two

These Tests from previous years cover less material than Test 2 will cover this Trimester, but provide some guideline as to what to expect. Another limitation of these previous Tests is that they were not online Blackboard Tests.

Final Exam

There is now no final exam in T2 2020.

This formula sheet was provided with the Test and with the Exam in previous years. Feel free to use it if you want to, when doing Test 1 and Test 2.

Previous Exams

Past exam papers are found on the library page: Go this page and EXAM PAPERS is an option at the top. Click and search for ENGR121. You'll find exam papers since 2014.


Or you can just go here for previous exams.

Here are some past exams and some model answers.


The textbook for ENGR 121 is: Engineering Mathematics: A Foundation for Electronic, Electrical, Communications and Sytems Engineers (4th Edition), by Anthony Croft, Robert Davison, Martin Hargreaves and James Flint, Pearson, 2012. We follow this book very closely, and it is also the text for ENGR 122 Engineering Mathematics with Calculus, so it will be very useful. It costs about $144 at Vic Books. It is recommended, not required, since the lecture notes are so detailed.

Also recommended, but not required, is Engineering Mathematics, by K.A. Stroud, with Dexter J. Booth, Palgrave MacMillan, London. About $133 at Vic Books.

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


Here is how your percentage mark is calculated, on which your final grade is based:

Assignments 25%, Labs 25%, Test One 25%, Test Two 25%.

If you do poorly on your assignments, we count 50% for your best test and we don't count the assignment mark.

Labs always count for a total of up to 25%, no matter how low the mark. There will be four labs.

You can miss up to two assignments without penalty as the best 6 of 8 assignments are counted. You can also miss one lab without penalty as the best 3 of 4 labs are counted. You are strongly advised to complete all assignments and labs, to maximise your grade for the course. By completing all assignments and labs in the first 6 weeks of the course, for example, you are then putting marks in the bank for the second half in case you get sick or otherwise indisposed later on. Also, the earlier assignments and labs tend to be easier but are worth the same marks!

Assignments and labs are fully marked, you can get very useful feedback from looking over your marked work.

Videos Of Lectures

We record all lectures to video. To see videos of lectures, please go to Blackboard, select ENGR121, then select Vstream Videos on the top left-hand panel. Recordings become available approimately 1 hour after the lecture finishes.


This schedule describes what we plan to cover during lectures in ENGR121.

Extra Help from Student Support

There is more help available from Vic's Student Support. They will help you with ENGR121, and they can also help advise on study habits and how to pass courses. Take a look at their website:
