Please register for this course on blackboard [link]. This will be used for entering test grades and for announcements, so if you do not register we will not be able to record your test grades.

Weekly tests

Please note that there are weekly tests in the Werkcolleges, which will count towards your final grade.

Teacher: David Holmes.


For the course "Linear algebra" (Lineaire Algebra) there are lectures ("Hoorcolleges") and exercise classes ("Werkcolleges"). In each werkcollege the last 20 minutes will be a test on the material from the course up to that point. This will count towards your final grade.

See timetable here.

The rooms of the lecture and werkcolleges are NOT the same every week; see here for details.

Required Literature

We will follow closely parts of the book "Linear algebra and its applications" by David Lay. Every student will need a copy of the book; for example, weekly exercises will be set from the book, and the tests and exam will contain similar questions.


Weekly tests

As noted above, there will be a short test held every week during the Werkcollege.


There is one exam for the course, after the end of the course (on 10 January). The exam will last 3 hours. It will cover material from the whole course, including that already covered in the weekly tests.

Calculating the final grade

Firstly, the weekly tests. There will be 6 tests in total. Your best 4 marks will count. Write W for the average of your best 4 tests. Write E for your grade on the final exam.

The total examination grade is is then the weighted average:

Final grade = 0.25*W + 0.75 * E.

Homework and classes

Each week, some problems from the book will be suggested. These will not be graded, and will not count towards the final grade. However, you are extremely strongly recommended to attempt all the problems - the problems in the short tests and the final exam will be similar, and past experience suggests that ability to do he homework problems is a very strong predictor of success in the course. The problems will be discussed during the classes, and you will have the opportunity to obtain help on problems you found difficult.

Office hours

Office hours of the lecturer will be from 09:30 -10:30 on Tuesdays (or by appointment) in room 233 in Snellius.

Content and detailed timetable

The first column is the date of the monday of the week (note the lectures are on Tuesdays and the exercise classes are on Fridays). The second column refers to chapters of the course book "Linear algebra and its applications" [Lay]. The final column contains the reccomended exercises from [loc.cit]; `H1.1:4,8' means exercises 4 and 8 from the end of chapter 1.1 of the book. Because many students have different versions of the book, this year I have copied the exercises into a pdf file (with link below) so that everyone is doing the same exercises, regardless of which edition they have.
