Didactic methods |
|
| Course lessons are taught by the professor in lecture halls, and followed by demonstration and solving of practical examples and mathematical equations/graphs. Additionally, students spend time on tutorials and lab-exercises. They resolve specific problems pertaining to their theses, using available or student-developed software. Goal of these activities is to enable students to get hands-on, practical experience in this area, as well as to gauge students' knowledge through assigned papers and exams (mid-term, as well as final). <br> |
|
Exams |
|
| During the course students earn points according to the following system: <br> - Attending classes and tutorials: 10 points; a student with more than three absences from lectures and/or tutorials will not be eligible to get these points. <br> - Home assignments, laboratory reports and/or final thesis: maximum of 10 points. <br> - Mid-term and final exams: a student can score up to 20 points on each exam (passing grade is 10 points). <br> During each of the two exams (time assigned is 90 minutes) students will solve simple questions - designed to examine whether students acquired basic theoretical knowledge - multiple choice problems, as well as one open-answer problem. Students who gain less than 20 points during one semester must re-take that course. <br> Students who earn 40 or more points during the semester are eligible for taking a final exam; the exam asks the student to discuss mathematical problems from the mid-term exam and home assignments, as well as to answer to simple questions related to general course topics. <br> A student can score a maximum of 40 points on the final oral exam (passing threshold is 20 points). A student who gets less than this minimum, must take a makeup oral exam. <br> A student who earns 20 points or more, and less than 40 points during the whole semester will have to take a makeup exam. The makeup exam is organized in the following manner: <br> - Written part is structured similarly to mid-term written exam, during which students will have to solve problems in which they failed on their mid-term exams (got less than 10 points). <br> - Oral part of the exam is structured in the same way as the oral part of the final exam. <br> |
