I base myself on special content that the student wishes to work with me. I prefer to know it a little in advance to be able to prepare my course. I base myself on what the student knows and then move forward little by little, tackling the subject point by point. I make sure that the student understands everything I explain to him over time so as not to lose him. After the learning phase, I always do a small verification test on the concept studied to see if the concept is acquired or if it is necessary for the student to rework it. Do not hesitate to contact me to see if I can deal with the concept you wish.
