### Teaching method

There are two hours of lectures and a lab session of three hours each week.

Lectures are problem-driven. They start with a concrete problem, which motivates the presentation of some computer systems topic, some data type or some programming language construct, and end with the complete source code of a program that solves it.

In the lab classes, students design, implement and test programs for solving simple problems in Science and Engineering fields.

### Evaluation method

**Assessment Components**

Assessment has two components: the laboratory component and the theoretical-practical component.

**Laboratory Component**

The laboratory component comprises three team programming assignments and one team programming project. Teams should have size two.

The evaluation of the programming assigments and of the project include an individual lab session where students are asked to demonstrate their knowledge about the code submitted.

The laboratory component grade (LComp) is the weighted mean of the three programming assignment grades (A1, A2 and A3) and the project grade (P):

In order to succeed (and to have access to the exam), it is required that:

**Theoretical-Practical Component**

The theoretical-practical component comprises two tests. If the weighted mean of the test grades is less than 8.5 and LComp >= 8.5, students can do a final exam. The tests and the exam are written, individual and closed-book.

The theoretical-practical component grade (TPComp) is the weighted mean of the test grades (T1 and T2) or the exam grade (Ex):

In order to succeed, it is required that:

**Final Grade**

The final grade (F), defined only if LComp >= 8.5, is:

- F = TPComp, if TPComp < 8.5;
- F = 0.4 LComp + 0.6 TPComp, if TPComp >= 8.5 .

All grades (A1, A2, A3, P, T1, T2, Ex, LComp, and TPComp) are rounded to the nearest tenth, except the final grade (F) which is rounded to the nearest whole number.
