  In this work, we study a sample of 600 engineering students in three
consecutive physics courses of different levels, according to their curriculum.
We focus on the most frequent students' misconceptions in newtonian mechanics.
It was administered the FCI test at the beginning of the academic semester in
each course. We use the taxonomy of misconceptions probed in the FCI test, and
through this, we establish correlations between the number of attempts in each
course, to explore if there are misconceptions that repeat in the students that
are on more than one attempt-in each course. The data reported in this paper
were analyzed using the method of dominant incorrect answers. The results show
that there is no relevant difference between a student on his first attempt and
a student on his third or more attempt, in each course, in terms of the most
frequent misconceptions.
