Methodologies
Methodologies   ::  
  Description
Tutorship of group Lecturer's office hours for solving student's difficulties with the course
Practicals using information and communication technologies (ICTs) in computer rooms Lab practices including software design for DS and experiments with real equipment
Problem solving, classroom exercises The objective of these sessions consists of exposing the student to simple, specific and example-based problem resolution which will play a vital role in streamlining their mastery of the course
Lecture Presentation of the core concepts about distributed systems along with resolution of word problems and exercises

Assessment
  Description Qualification
Lecture Attendance is mandatory 1%
Practicals using information and communication technologies (ICTs) in computer rooms Attendance is mandatory 1%
Problem solving, classroom exercises Attendance is mandatory 1%
Practical tests Submission of Lab Book whenever the instructior requests it 10
DS Pro (optional Practice submission) 10
Extended-answer tests Two Term Exams (Term 1 and Term 2). Weight distribution for final grade:

Te 1 = 70%

Te 2 = 30% 		72%
 
Other comments and second call

Student attain a passed grade if the grade to each of the two Term Exams is "passed", i.e., 5 points or greater. Both term exams must be passed for the final weighted, passed grade is granted.

Final Grade =
0,72 * Weighted average (70/30 of term exams if both are passed)

+ 0,15 * Grade to the practices and regular Lab attendance
+ 0,10* DSPro
+ 0,03 * Attendance to Lectures, Problem sessions and tutorials
