Note that the sections 53, 54, 55 in the fifth edition are moved to sections 56, 57, 58 in the sixth edition!

Problem sessions The problem sessions are held on Tuesday 10-12 and Friday 10-12, beginning

January 24 th . The problems will be chosen from the list of recommended exercises on the home

page. All these are important, and most of them will be discussed during the problem sessions. For

Solutions Algebra home exam March 2020.pdf

New (March 12th)!

As the written exams will be carried out at home there will no longer
be exercises where the students should reproduce proofs from Durbin's 
book. The two exercises 5 and 6  will instead be problems of the same
kind as exercise 1- 4.
The president of Chalmers has, as is well known, decided that all hall exams during the exam week 
will be done at home. Here are some guidelines.
Rules for the exam (March 13th)
The examination must be conducted individually, that is, cooperation is not allowed. Due to the changed circumstances, all aids are allowed regardless of what is written on the exam. Checks on plagiarism will be carried out.
You have 4 hours to complete the exam. Solutions are written on paper, or digitally on a digital writing pad if you have access to it. Never write more than one task on each sheet. After 4 hours, you have 30 minutes to scan / photograph your solutions and organize and submit your solutions according to one of the following ways in order of priority:
1. A single pdf file where the pages are arranged in the order of the questions
2. Image files (jpg or png) or pdf files where each file contains solution to just one question and named according to "Question 1", or "Question 1 page 1", Question 1 page 2 "etc if there are multiple pages to a question. You who have a certificate for extended time will have 6 hours to complete the exam and after that 30 minutes for you to submit according to the same instructions as above. When you submit, it will be stated that the exam is submitted late and if you have not already notified the examiner that you are entitled to extended time, you should do so afterwards.

NEW INFORMATION! Information about the Algebra exam 2020.docx

There is a written exam in March. There are two re-exams in 2020. There are four exercises in the

exam about applying basic theory in the course, and two exercises about stating important

definitions and theorems and giving proofs to variants of them. Each exercise is worth 4 or 5 points

and there are 25 points in total. No extra aid (textbook or internet) is allowed during the exam.
