This page contains all information for the exam for IS1200 and IS1500 that takes place in January, 2025. All the information below has been given out before, during lectures and via announcements. However, this page will also be available during the exam (digitally in Canvas).

The registration for the exam is on Ladok (and not anymore on Canvas).

This is the last opportunity to be examined on the MIPS architecture.

Basic info before the exam

The examination is computer-based, where you solve the assignments on your own computer, using a Linux-based virtual machine (VM). The rationales for this change compared to a paper-based exam are: better examination (programming for real), harder to cheat (individual exercises), and faster to correct (large parts are automatic).
The examination takes place at KTH Kista.
You sign up for the computer-based exam using LADOK (as normal exams).
To get familiar with the virtual machine, please see the page "Virtual Machine Installation" on Canvas. You must try it out and test that you can compile MARS and C programs using the UNIX shell etc. before the exam. There will not be time to learn how to do this during the exam. Also, please make sure to try out the test exam, which is available under "Quizzes" on Canvas.
Please make sure to download the latest version of the VM.
If the VM does not work or you do not have a laptop, then you can request a computer from KTH. To obtain a computer form KTH, you must answer this questionnaire within the exam registration period (Nov 28 - Dec 12): https://www.kth.se/form/dator-is1200-is1500

Exam structure

The structure of the exam will be the same as previous exams, with the main difference that all the tasks will be submitted via a quiz in Canvas (inside the virtual machine). Another difference is that you can/should test your programming exercises with the compiler before you submit your solution. Most of the exercises will be corrected automatically (although not directly when you submit the exam/quiz), which means that if they cannot be compiled, you will not pass that task.
It is recommended that you study old exams and that you also try to implement and run programs from old exams using the virtual machine.
All exam questions will be given in English. It is, however, allowed to answer in either Swedish or English.
Note that everyone gets different versions of the exam (different questions and/or task values). We have evaluated all questions to make sure that they are approximately at the same level of difficulty.
NOTE: When the exam time starts, your exam will be available under tab "Quizzes". You will receive the password by the exam invigilator when the exam starts.

During the exam

Several of the pages on Canvas will be disabled during the exam. But this page and the quiz page will be available during the exam.
You submit your final solutions in Canvas. But, before you enter the final results, you can use either normal papers or the computer (using the virtual machine) to solve the tasks.
Note that Canvas continuously saves your quiz answers, so you do not have to click save.
Note also that you MUST NOT submit your solution until you are completely done. It is very complicated to resubmit if you have already submitted. If you submitted by mistake, you need to contact the exam invigilator. Note that you need to enter all tasks again in such a case, so please do not submit until you are completely finished with the exam.

Handing in the exam

When the time is up, you need to submit the exam before the exam time ends. However, if you are finished with your solution before the time ends, you may submit before the deadline.

Allowed aids

One sheet of A4 paper (both sides) with notes. The notes must be handwritten by you and may not have been copied.
You must use the VM supplied in the course. No other software is allowed to be used.
The MIPS sheet, which is provided as part of the VM. There will also be a printed copy available.
You are not allowed to install anything on the VM.
You are allowed to use pen and paper when solving the tasks. However, all results must be entered in Canvas using the VM.
You are not allowed to use headsets or any other equipment. The ordinary rules for normal written exams also apply here.

Exam structure

The main structure of the exam is similar to previous years. You will also be able to get sub-points on some of the exercises. The main structure is as follows:

Part I: Fundamentals

Max 40 points (IS1200) and max 48 points (IS1500).
8 points for each module.
Short questions with short answers.

Part II: Advanced

Comprehensive questions.
Discuss, analyze, and construct.

Note that the exam in Canvas says that it consists of 57 points for IS1500 and 49 points for IS1200. For IS1500, the fundamentals (Part I) consist as before of 6 modules x 8 points = 48p, and for IS1200 5 modules x 8 points = 40p (IS1200 students do not have module 3). The extra 9 points (48+9=57 for IS1500 and 40+9=49 for IS1200) are for the advanced part. For each of the advanced questions, you will actually get grade F, S, G, or VG, and not points (see below). However, the Canvas quiz system does not let us use these letter grades within the quiz. This is why you see the 9 extra points for the quiz in Canvas. The final exam letter grade will be entered in a separate Canvas assignment.

Grading

Pass criteria:

To get a pass grade on the exam (A, B, C, D, or E), it is required to pass Part I of the exam. For IS1500 students, it is required to get at least 2 points on each module (excluding bonus points), and in total at least 36 points on Part I (including bonus points). For IS1200 students, it is required to get at least 2 points on each module (excluding bonus points), and to get at least 30 points in total on modules 1, 2, 4, 5, and 6 on Part I (including bonus points). Note that there is an explicit mapping between the official learning goals of the course, and the modules. That is, the criterion to pass the course is to have sufficient knowledge on all modules. The learning goal of explaining technical solutions orally and in writing is examined during labs and in the project.

Grading criteria:

Passing only Part I gives in total grade E on the exam. To get a higher grade (A, B, C, or D), the student needs to show knowledge within three different abilities, each represented as a separate question in Part II.

Question 1: Discuss: Test the ability to discuss and compare different concepts present in the course. The focus of the discussion is on module 6, but other concepts from modules 1, 2, 4, 5 may also appear on the exam. The question is graded in three levels S, G, and VG, with the following criteria:
- Satisfactory (S): Some of the concepts in the question are clearly explained.
- Good (G): Basically all concepts in the question are clearly explained, and some of the concepts are related to each other, by discussing similarities and differences.
- Very Good (VG): Basically all concepts in the question are clearly explained, and all of the concepts are related to each other, by discussing similarities and differences.
Question 2: Construct: Test the ability to correctly construct larger C and/or Assembly programs. The focus on the construction question is on modules 1 and 2. The question is divided into three tasks/functions, each corresponding to one of three levels of difficulty: L1, L2, and L3. The question is graded in three levels S, G, and VG, with the following criteria:
- Satisfactory (S): The task at level L1 is solved correctly.
- Good (G): Either the task at level L2 or the task at level L3 is solved correctly.
- Very Good (VG): Both the tasks at level L2 and L3 are solved correctly.
Question 3: Analyze: Test the ability to analyze C and/or Assembly programs with respect to pipelines and/or caches. The focus on question 3 is on modules 4 and 5. The question is divided into three analysis tasks, each corresponding to one of three levels of difficulty: L1, L2, and L3. The question is graded in three levels S, G, and VG, with the following criteria:
- Satisfactory (S): The task at level L1 is solved correctly.
- Good (G): Either the task at level L2 or the task at level L3 is solved correctly.
- Very Good (VG): Both the tasks at level L2 and L3 are solved correctly.

In summary, the final grades on the exam are given as follows:

Grade A: Passed Part I, performed an advanced project, and received three VG or two VG and one G on part II.
Grade B: Passed Part I, performed an advanced project, and received one VG and two G or two VG and one S on part II.
Grade C: Passed Part I, performed a basic or advanced project, and received three G or two G and one S or one VG and two S or one VG and one G and one F or two VG and one F or one VG and one G and one S on part II.
Grade D: Passed Part I, performed a basic or advanced project, and received three S or one G and one S and one F or two G and one F or one VG and one S and one F or one VG and two F or one G and two S on part II.
Grade E: Passed Part I, performed a basic or advanced project.
Grade FX: At least 36 points (for IS1500) or at least 30 points (for IS1200) on Part I, and at most one module with less than 2 points.
Grade: F: otherwise

Bonus points: It is possible to get up to 4 bonus points on the seminars. These bonus points will be added to part I, fundamentals. The points will not be added to a specific module, but is counted when summarizing the total points of Part I. The bonus points are not shown in the quiz.

Advanced project: To get grade A or B on the written exam, the student must have completed an advanced project before the exam and within the same course year. That is, the accomplishment of completing an advanced project gives the possibility to get grade A or B on the ordinary exam when the project was completed, and on the two following retake exams. The status of your project (basic or advanced) is not shown in the quiz, but will be used when calculating your final grade after the exam.
