SUBJECT ASSESSMENT

Exams are graded between 0 and 10 points. The course would be passed if:

1st- Final exam qualification (F) is equal to or higher than 4 points.
2nd- Course work qualification (C = 0,625 x C1 + 0,125 x C2 + 0,25 x C3) is equal to or higher than 5 points, and
3rd- Final qualification FQ = 0.60 F + 0,4 x C is equal to or higher than 5 points.

If the final examination mark is lower than 4 points, C1, C2 and C3 parts will not be considered, resulting FQ = F

This assessment system applies in both, first and second exam calls.

SKILLS ASSESSMENT

C1-Manual drawing practices and assignments: FB5, CB5, CG6, CT2, CT15, CT17, and CT19
C2-CAD practical: FB5, CB5, CG6, CT2, CT4, CT15, and CT19
C3-Tutorial group classwork: FB5, CG6, CT14, CT15, and CT19
F-Final exam: FB5, CB5, CG6, CT2, CT14, CT15, CT17, and CT19

LESSONS ATTENDANCE
Attendance at al least 80% of the practical sessions of the current course will be a requirement for taking exams in both first and second, and extraordinary calls.

SECOND CALL
The same rules and conditions than the first call apply here.

EXTRAORDINARY CALL
The same rules and conditions than the first and second calls apply here.

COMPATIBILITY
Students who could not attend practical sessions due to excusable reasons or legal exemption, must communicate this circumstance to be assigned an alternative learning method.

EXAM REVISION
Students can review their corrections and learn of qualification criteria. Dates for exam review will be announced according to current regulations.
Exam review could be carried out either on a face-to-face basis or remotely through MS Teams.

In the event of fraudulent practices in exercises or tests, the provisions of the Regulations on the Evaluation of Students' Academic Performance and the Review of Grades shall apply.

The total course workload is estimated at 150 hours (6 ECTS credits). 58 hours are scheduled for classroom activities (lectures, tutorials, practicals and examinations); students will assign 92 additional hours of individual work. Time distribution is:

- Lectures: 28 hours in the classroom and 42 hours of personal work.
- Seminars: 6 classroom hours and 9 of personal work
- Laboratory practicals; 15 classroom hours and 8 of personal work
- Group tutorials; 2 classroom hours and 8 of personal work
- Individual tutorials: 2 classroom hours and 3 of personal work
- Examination and review: 5 classroom hours and 22 of personal work

The course progression requires punctual study to assimilate the new concepts explained in each session.
The development of spatial visualization skills requires time to be exercised. Thus, students must follow the activities suggested at the beginning of the course. Students lacking a previous background in Technical Drawing must realize the extra effort needed, particularly during the first weeks.

Other recommendations:

-Lesson attendance
-Punctual practice work
-Tutorial advice to solve doubts and difficulties, and to pick up additional exercises
-Use of complementary materials through the Learning Management System
-Consult the recommended bibliography.

Classes are presented in Galician language. One group will be taught in English.
The Learning Management System is used to complement the learning process.
Software programs AutoCAD for Windows and SketchUp Free will be used throughout the course. Both are available and free for the students.
The use of Windows computers is recommended as the USC does not provide support for other operating systems.
