Mechanical Engineering BSc

Lecture:

Wednesdays 16:15 - 18:45, Building R, Room R512; and (CHANGED!) Thursdays 18:00-18:45, Building R, Room R513

Practice:

(CHANGED!) Thursdays 16:15 - 17:45, Building R, Room R513

Materials: The lecture does not follow any (English) book, but different topics can be found in the following book:

Thomas' Calculus (edited by J. Hass, C. Heil, D. Weir), 14th Edition, Pearson, 2018.
I. Farago, A. Havasi, I. Mezei, P. Simon: Introductory Course In Analysis, can be downloaded from here . (Chapters 10-12 and 15)
Strang: Introduction to Linear Algebra, 5th Edition, 2016.

Requirements:

1. For the practice part:

During the semester, there are going to be two midterms, 20 points, 90 minutes and 5-5 exercises each.
You need to get 30% (6 points) on each to get a signature.
For the proposed times of the midterms, see the schedule below.

There is also going to be a retake, possibly on the last week (Week 14) and a re-retake on Week 15.
Note though that the points you get on the retake will erase the points of the previous midterm, even if the points are lower.
If your first try was succesful (so you got at least 6 points) but you did not get 6 points on the retake, you will get 6 points for the 2nd one.

2. For the lecture part:

The course ends with a 120-min long written exam.

It has two parts: the first part consists of a test of yes-no questions. The list of all possible questions.

In the second part you will have to solve 5 exercises that will be similar to midterm-exercises.

You can get 60 points on the exam.

Your final points are the sum of your points at the exam and the points of your two midterms.

Mock exam

Grades at the end of the semester: (the points are subjects to modification, but only downwards)

40-54: grade 2
55-69: grade 3
70-84: grade 4
above 85: grade 5
