Frequently asked questions

Who should use DelftPrep?
DelftPrep is designed for students who are serious about increasing their chances of getting into TU Delft's Aerospace Engineering or Computer Science programs. If you want to approach the selection test with confidence and plenty of high-quality practice material, DelftPrep is for you.
How do I access the practice materials?
Within 10 minutes of your purchase, you will receive an email with instructions to set up your account. The practice exams will be accessible through the ANS exam platform.
Do I need DelftPrep to prepare for the selection test?
No, you don’t need DelftPrep to succeed. The selection test evaluates high school-level knowledge, which you should already have. TU Delft also offers precalculus courses you can use to prepare.

However, DelftPrep simplifies the process by providing a structured approach, saving you time and effort in figuring out what to study. During a busy period when high school students are also preparing for their final exams, we act as a one-stop shop with a curated set of high-quality, exam-style questions, helping you focus on what matters most.
What package is right for me?
The needs of every student are different. If you have any hesitation please feel free to contact us at contact@delftprep.nl
Why is your acceptance rate 62% and not higher?
The TU Delft Aerospace Engineering program is very competitive. The acceptance rate for the average applicant is only about 22% (and that’s just among students who complete every step of the selection process; the real baseline is even lower).

With our program, our students currently achieve a 62% acceptance rate, which is almost 3x higher than average. We are constantly improving our materials and support to help students maximize their chances. We’re also with them every step of the way; if they have questions, worries, or need advice, they can always reach out to us directly.
What is the First Year Material (FYM)?
TU Delft provides study materials each year that reflect the topics from the first year of the Aerospace Engineering bachelor. These topics typically include:
- Aerospace structures and materials
- Aerodynamics
- Flight mechanics
- Space.

The material is a mix of sections from a digital textbook and video lectures. TU Delft releases the FYM only a few weeks before the exam on purpose; so they can test how quickly candidates learn new material independently.
Why does DelftPrep update the FYM exams?
TU Delft changes the FYM syllabus each year. That’s why we update all our exams as soon as it’s published (usually in January) — typically within a week of release. Until then, our platform uses the previous year’s material.

It’s generally not necessary to practice FYM exams before TU Delft publishes the new one, since the material often changes. However, some topics do overlap year to year, so if you want a head start and don’t mind practicing with material that might not appear on the exam, you can begin earlier. From our experience, it’s also completely fine to start preparing once the new FYM is released and our exams are updated.
Is payment secure?
We use Stripe for all payment processing. Stripe has been audited by a PCI-certified auditor and holds a PCI Service Provider Level 1 certification, the most stringent in the payments industry.
When should I purchase DelftPrep?
You can purchase DelftPrep anytime before the selection exam in February/March 2026. Purchasing earlier gives you more time to practice and get the full benefit of our materials. From our experience, students who start earlier, especially those who complete the full 40 hours of practice, have a higher chance of success. Some students like to get an early start in September, while many others begin in January, which is when we recommend starting more intensive preparation.
How is the online crash course conducted?
Our Online Crash Course unfolds through live sessions hosted on Google Meet.
Am I allowed to use DelftPrep to prepare for the selection process?
Yes, absolutely! While TU Delft discourages the use of third-party commercial companies or tutoring for the selection process, DelftPrep is is designed to support individual students who want to be well-prepared.

Our platform offers plenty of practice questions, structured to cover key exam topics, along with crash courses that address material not always covered in class and provide valuable exam tips. We also help students practice performing under time constraints, which many find the hardest part, and familiarize them with taking exams online to improve speed and confidence. Additionally, we ensure students are comfortable with the English terminology used in the exam, helping them feel thoroughly prepared while respecting the integrity of the selection process.
What is your refund policy?
Due to the non-returnable nature of our digital products, all purchases are non-refundable. We offer a free trial to ensure you understand what you're purchasing. You can request a free trial by sending an email to contact@delftprep.nl with the subject line “Free Trial Request”, and we will provide you with trial access.
Are these the real past exams?
No. TU Delft does not release past exams. We create our practice tests to be as accurate as possible by interviewing first-year students each year and adjusting our format and content based on their feedback. Our exams are updated annually to reflect the most current information available.
How accurate are your exams?
We make our exams as accurate as possible. If TU Delft changes the format from one year to the next, we may not always have time to perfectly replicate those changes, though we do our best. Fortunately, the exam is more about mastering the content and problem-solving than about minor formatting differences. By practicing with our exams, students are still extremely well-prepared for the real test.
When should I start preparing?
The earlier you start, the better. From our experience, students who spread their preparation over a longer period feel less stressed and more confident.

We generally recommend starting intensively in January, once TU Delft publishes the new First Year Material and we update all our exams.

However, you can safely start much earlier (e.g. September, October, November) by focusing on the math and physics exams, since those subjects do not change from year to year. The only section that changes annually is the First Year Material (FYM). If you want a head start, practice math and physics early, then add FYM once TU Delft publishes it.

We’ve also noticed that students who spend more time with our practice exams tend to have a higher chance of getting accepted. On average, it takes about 40 hours to work through all of our material, and candidates who complete this tend to perform very well. That’s why it’s important to time your preparation so you can realistically fit in those 40 hours before the exam in March. We know the final year of high school is demanding, so planning ahead makes a big difference.
Is DelftPrep affiliated with TU Delft?
DelftPrep operates independently from TU Delft, comprised of alumni well-versed in the TU Delft admission process.
