In order to obtain ECTS-Credits you need to both gain admission to the exam and you need to pass the exam. The exam is passed if you obtain a score of at least 50% in it.
The Final Examination will be held on February 19 (Monday), 2018 from 10:00 am onwards at E-011
The 2nd Examination: April 27, 2018 (Friday), from 12:00 pm onwards at M-001.
You are expected to hand in all the assignments in due time, every week on Wednesday at 11:00 am. The assignments must be done by everyone in the group. The assignments should be handed in a pdf format with all valid source code and graphs if necessary. Assignments will be treated incomplete if any part of the solution is missing. Students need to accomplish at least 60% of the assignments in order to attend the final exam. Plagiarism is strictly forbidden and will result in disqualification from the final exam, of both sides of the plagiarism (copying and being copied). Students are also expected to explain some of the assignments.
The SVN repository to submit your assignments is : https://svn.uni-koblenz.de/westteaching/webscience-1718/GROUPNAME
Replace GROUPNAME with your group name in lower case letters. Please remember to have your assignments in different folders under "solutions" .
Last Year Students
Students who failed to secure passing grades last year can directly appear for the examinations this year. However, it is advisable to participate in the course and the tutorials.
For assignments, you have to make a group of 2-3 to be in a team. To create your teams, you can click here.
