Eligibility for exams

According to General Evaluation Rules of FEUP

Calculation formula of final grade

- Assembly and disassembly of an engine (5% of the Final Mark)- a grade from 0 to 20, depending on students’ participation on this assignment
- Problem solving with EES software (15% of the Final Mark) - a grade from 0 to 20
- Final Exam (80% of the Final Mark) - a grade from 0 to 20. Theoretical part (30% of the Final Exam Mark), practical part (70% of the Final Exam Mark)
Practical part of the exam (open book exam). Theoretical part of the exam (closed book exam).
