Aerospace Engineering TU Delft - Selection Exam Preparation
The TU Delft Aerospace Engineering Bachelor is one of the most prestigious bachelor programmes the Netherlands has to offer. With it being highly sought-after by students all around the globe, there is a highly competitive selection procedure which needs to be completed to get admitted to this popular degree. A massive part of this admission procedure is the selection exam, consisting of three different tests: Mathematics, Physics and First-Year Material. As a cum laude graduated Aerospace Engineer at TU Delft, who has also been tutoring since 2017, I have a lot of valuable experience and knowledge of the program to help you out with the right preparation to get in. Moreover, after having successfully helped two international students get a spot last year, I have decided to continue preparing an additional custom lesson plan for each student, with the admission syllabus as its basis. With my calm and stepwise explanation, weaker topics will be addressed and your solution procedures will be polished. Each lesson will either be theory, exercise-based or an opportunity to talk about the admission, what to expect from the study and whether it is a right fit for you.
