The Virtual Campus will be used to provide students with all the materials that the teaching staff deems necessary for the learning process: course syllabus, lecture presentations, problem sets, links between course content and various recommended textbooks, etc.
Students under both continuous assessment and single assessment modes:
In accordance with the course objectives, students will be required to complete a series of guided learning activities in order to acquire the established knowledge and competencies. These activities will include:
In-person lectures:
During part of these sessions, the instructor will highlight selected theoretical aspects of the various course topics. Another part of these classes will take the form of seminars, dedicated to addressing students' questions—whether theoretical content, problem-solving, or course organization matters.
In-person problem-solving classes:
These sessions will involve presenting and discussing solutions to a set of problems proposed by the instructor, based on students’ independent or group work. Special emphasis will be placed on active student participation.
Laboratory sessions:
There will be 12 laboratory sessions, each lasting 4 hours, designed to ensure students acquire basic techniques of an organic synthesis laboratory. The content of these sessions will be tied to the topics covered in prior theoretical classes. Attendance at all 12 sessions is mandatory. There is also a mandatory introductory lab session scheduled.
Note:
During the in-person lectures, several assessment activities ("evidences") will take place throughout the course. Student participation will be encouraged through case resolution and Q&A. These assessment activities will not be mandatory for students enrolled under the single assessment mode.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

1. EVALUATION
1.1. Students in Continuous Assessment Mode:
The final overall grade for this course will be calculated based on the following three components:
1.1.1. Exams (75% of the final grade):
The exams will assess the knowledge covered in the course syllabus, with particular emphasis on problem-solving skills.
Throughout the course, each midterm exam will include questions on all content covered up to that point. These exams will carry increasing weight in the final exam grade:
To pass the course through midterms, students must obtain a minimum score of 4 out of 10 on the third midterm and an average weighted score of 5 out of 10 across the three exams.
1.1.2. Laboratory sessions (15% of the final grade):
Assessment will be based on interest, experimental skills, and results achieved during lab sessions (40%), and the lab exam score (60%).
Lab sessions are mandatory. A maximum of two sessions can be missed due to justified medical reasons. To pass the lab component, students must obtain at least 5 out of 10 in both the lab sessions and the lab exam.
If a student scores below 5 on the lab exam, they must take a retake lab exam on the same day as the retake theory exam. To be eligible, the student must have taken the original lab exam.
SAFETY WARNING: Any student who, due to negligent behavior, causes a serious safety incident may be expelled from the laboratory and fail the course.
Students retaking the course (second enrollment or beyond) who passed the lab component in a previous year under the required conditions do not need to repeatthe labs, and their previous lab grade will be maintained.
1.1.3. Other Evidence (10% of the final grade):
Throughout the course, students may be assigned exercises, quizzes, or other small tasks, to be completed individually or in groups, in class or outside, at the discretion of the instructor.
Any uncompleted assessments will be graded as 0.0 out of 10 when calculating the average.
1.2. Students in Single Assessment Mode:
The final overall grade will be calculated based on the following two components:
1.2.1. Final Exam (85% of the final grade):
The exam will assess the course content, with emphasis on problem-solving skills.
It will be scheduled on the same day as the third midterm for students in the continuous assessment mode.
1.2.2. Laboratory Sessions (15% of the final grade):
The same conditions apply as for students in the continuous assessment mode.
2. TO PASS THE COURSE
2.1. Students in Continuous Assessment Mode:
2.1.1. Conditions:
a) Have a weighted average of at least 5 out of 10 for the three midterms and a minimum of 4 out of 10 in the third midterm. Students taking the retake exam must score at least 5 out of 10 on it.
b) Have attended the lab sessions (as detailed in section 1.1.2) and scored at least 5 out of 10 in both lab components used to calculate the lab grade.
c) Achieve an overall average of at least 5 out of 10 in all graded components.
2.1.2. Retake Exam:
There will be a single retake exam for students who did not pass via midterms. It will cover the entire course content.
Students who passed through coursework may retake the retake exam to improve their grade. In this case:
To take the retake exam, students must have taken at least two of the three midterms.
To pass via the retake exam, students must score at least 5 out of 10. The final grade will be calculated as follows:
If the retake exam is not passed, the maximum final grade (after applying the formula) will be 4.8, meaning the course will be failed.
If a student attends the retake exam but does not submit it, the final grade will revert to the midterm average (a zero will be assigned for any missed midterm).
There will also be a retake lab exam for students who did not score 5 out of 10 in the original lab exam. The 40% related to in-lab performance and results cannot be recovered.
To sit the lab retake exam, students must have taken the original lab exam.
Passing the lab exam is mandatory to pass the course.
2.2. Students in Single Assessment Mode:
2.2.1. Conditions:
a) Score at least 5 out of 10 on the final exam.
b) Attend all lab sessions and obtain a minimum of 5 out of 10 in both the overall lab grade and its two individual components.
c) Achieve an overall average of at least 5 out of 10 in all components.
2.2.2. Retake Exam:
There will be a single retake exam for students in single assessment mode, scheduled on the same day as the continuous assessment retake exam.
Students who passed but wish to improve their grade may take it. If:
The exam will cover all course content.
To pass, a minimum score of 5 out of 10 is required. The final grade will be calculated as:
If the retake exam is not passed, the maximum final grade possible is 4.8, resulting in a course fail.
There will also be a retake lab exam for those who scored below 5 out of 10 on the original lab exam. The 40% for in-lab performance and results is not recoverable.
To take this exam, students must have attempted the original lab exam.
Passing the lab exam is mandatory to pass the course.
3. A STUDENT WILL BE CONSIDERED "NOT ASSESSED" IF:
a) First-time enrollees in continuous assessment mode: Did not take any midterm exams nor the lab sessions.
b) Repeat students in continuous mode with previously passed lab component: Did not take any midterms nor the lab in the current course.
c) First-time enrollees in single assessment mode: Did not take the final exam nor the lab sessions.
d) Repeat students in single assessment mode with previously passed lab: Did not take the final exam nor the lab in the current course.
IMPORTANT NOTICE:
If a student is caught cheating in any assessment, they will receive a score of 0 for that specific test.
