- © 2022 IEEE.The main purpose of this research is to decrease the anxiety levels of undergraduate engineering students during a Mathematics exam; those anxiety levels are intended to be decreased through a five-week Mindfulness program. We propose a quantitative measurement of anxiety levels using EEG signals from a portable device, those raw signals are processed using chaotic descriptors. Levels of anxiety are measured before and after a Mindfulness program before solving a couple of online Advanced Mathematics (complex variable) exams. Critical thinking skills are also measured from EEG before and after the Mindfulness program during a Problem-Based Learning assessment. Results show a decrease in anxiety levels and an increment in critical thinking skills.
