As a current Master's student in Aerospace Engineering at TU Delft, I have successfully navigated the entire Bachelor's curriculum and the competitive selection procedure, so I am fully equipped to guide you through the study plan and specific admission requirements. I offer personalized tutoring sessions designed to ensure comprehensive preparation for the entrance exams. These classes include a detailed review of key concepts in Mathematics and Physics, intensive practice with relevant exercises, and specific strategies to tackle the test effectively. I also place a dedicated focus on mastering the First Year Material (FYM) section (often the most challenging and unfamiliar part for applicants) to help you build the confidence and skills necessary to succeed. Furthermore, I am happy to discuss the degree program itself and explore the opportunities available in Delft to help you prepare for your future student life.

As an advanced user of Rhino & SketchUp, I can say that I admire Rhino's crazy capabilities that revolutionize 3D modeling, especially in the organic realm, along with SketchUp's cleverness and speed in modeling. I've taught both at a university and have been using them for more than 8 years in my projects. Hence, I can teach you the best of both worlds with versatile commands, features, and tips and tricks, whether you're a beginner or just need some push.

80% of my students got accepted in the 2025 exam, I am sure I can help you out in the 2026 exam!

TU Delft is Europe's most prestigious university for aerospace studies, preparing some of the best engineers. However the selection procedure is tough and demanding, and only those prepared have a chance to succeed.

As a TU Delft student, I know from first hand how stressfull this process is, and can therefore help you succeed in the preparation of these exams. I have previous experience as a tutor back in high school, helping students improve their grades from Cs to As.

Moreover, I have an extensive knowledge on the subjects tested on these exams, having taken them myself, completed the courses at university with excellent grades and teaching over 10 students for the entrance exam.

Throughout the class, I will use a presentation to explain the main concepts of each exam (Maths, Physics and Aerospace Engineering), focusing on those subjects the student is struggling with most. After this, I will help the student complete some practice excercises, and then assign extra practice to complete on their own time. These exercises will then be reviewed in the following class to ensure the topics have been understood.

I am looking forward to help you in your journey as an aerospace engineer!

This course is designed for high school and college students seeking to strengthen and better understand the core subjects: mathematics, physics, electricity, mechanics, and thermodynamics.

The approach is 100% practical: we start from the topics you cover in class and apply them to real-life examples. You'll see how seemingly abstract equations and theories become experiments, prototypes, and simulations that explain phenomena from everyday life and modern science.

Upon completion, you will be able to:

Understand and apply mathematical concepts to real-life problems.

Relate physics principles to everyday situations and simple projects.

Understand the fundamentals of electricity, heat, and mechanics with practical exercises.

Improve your logical reasoning and test confidence.

Certified Professional Coach, middle and high school teacher, and former expert in engineering and project management, I have supported both young students and future engineers in their journey.

This diversity allows me to offer support tailored to each age and need:

For younger children (from 10 years old), I work on the fundamental basics: reading, writing, mental and written calculation, oral expression, basic English, logic.

For middle and high school students, I offer support in scientific subjects, homework help, and personalized academic coaching (organization, memorization, stress management, guidance).

My approach is that of the modern tutor: a relationship of listening, trust and progress, where the student is an active participant in their learning.
