From Istanbul to Mainz: My TestAS preparation story for medical school in Germany

A young woman using TestAS preparation books to prepare for the TestAS

My TestAS success story

My name is Elif. I’m originally from Istanbul but currently in my third semester of medical studies at Johannes Gutenberg University (JGU) in Mainz. One of the key factors that helped me get here was passing the TestAS exam, which is a standardized aptitude test required by many German universities. What made the biggest difference for me on the exam was using edulink’s TestAS preparation books to prepare which gave me the edge I needed to get into medical school.

Here’s a bit about my journey – and how you can follow a similar path.


I always knew I wanted to become a doctor. With both of my parents working in healthcare, the profession felt like a natural direction. However I also wanted to build something for myself so I decided to study abroad and build a future in a different country.

Germany stood out for several reasons:

  • Little to no tuition fees at public universities.
  • A globally respected medical education system.
  • Safe, well-structured, student-friendly cities.
  • Opportunities for long-term work and residence in the EU.

However, applying to study medicine in Germany as an international student is incredibly competitive.
I knew I had to strenghten my application, and that’s when I discovered the TestAS exam.


The TestAS (Test for Academic Studies) is used by many German universities to assess the academic readiness of international applicants. It’s not about subject knowledge — it’s about how you think.

What does the TestAS consist of?

  • A Core Test that evaluates logical reasoning and problem-solving
  • A Subject-Specific Module (I chose Mathematics, Computer Science, and Natural Sciences)

Why should I take the TestAS?

  • Add bonus points to your university application.
  • Some universities require it, especially for competitive fields like medicine
  • Stand out and add credibility when you’re applying with a foreign high school diploma

At JGU Mainz, my top 10% score in both the Core and Subject-Specific Module of the TestAS gave me a significant advantage in the admissions process.


When I first saw a sample of the Core Test, I was surprised — it was unlike anything I had studied before. It included abstract logic and complex patterns. That’s when I found edulink’s TestAS preparation books, and they really helped me approach the test more strategically.

What I appreciated the most about the series:

  • Clear explanations of the test structure and question types
  • Tips for managing time during the exam
  • Practice questions that reflect the actual TestAS format
  • Advice tailored to students aiming for competitive degrees like medicine

What stood out about these books:

  • Designed specifically for international students applying to German universities
  • Covers Core Test and all major subject modules
  • Includes realistic practice questions, smart strategies, and step-by-step explanations
  • Offer guidance for high-demand programs like medicine, engineering, and business

In my experience, these books aren’t just theory — they are the closest thing to real TestAS experience you’ll find.


Besides the books, I also got one-on-one guidance from the edulink team, which helped me:

  • Understand how universities use TestAS scores
  • Decide which subject module to take for medicine
  • Target the universities where I had the highest chance of admission
  • Navigate the bonus point system

Their insights were especially helpful because requirements can vary between universities — and understanding those differences is key.


Yes — and I did. At the time, I didn’t feel confident enough in my German to take a standardized test. The English version of the TestAS worked perfectly for me.

After arriving in Germany, I focused on learning the language. Now:

  • I study entirely in German
  • I take part in lectures, seminars and labs
  • I’m comfortable speaking both academically and socially
  • And yes — my friend circle is both international and German

Tip: Even if you take the TestAS in English, start learning German early. Aim for at least B2 level before starting your degree — especially in medicine.


You should take the TestAS if you’re applying to:

  • Medicine
  • Engineering
  • Computer science
  • Psychology
  • Economics or business

For some programs, it’s mandatory. For others, it can improve your admission chances through bonus points.

But more than that, it shows universities you’re ready to succeed in a German academic environment.


If I hadn’t taken the TestAS — and prepared properly — I don’t think I’d be in medical school today.

If your dream is to study in Germany, don’t leave it to chance. Prepare strategically:

  • Use high-quality TestAS prep materials (like those from edulink)
  • Practice regularly
  • Understand your strengths
  • Ask questions and seek support
  • And above all: believe in your ability to succeed

  1. Arjun

    I would like to know if you sell German language preparation testas books for medicine. If yes, then how much do they cost and where can I find them?

    1. For medicine, there are two TestAS test types:
      • The paper-based test, where you would need to take the Natural Science module. Please beware that some universities ask for the test to be taken in German. Others allow either of the languages. If you speak both languages, taking the test once in German and once in English could be meaningful, esp. since medicine is a competitive major.
      • The digital test, where you would need the Medicine subject module.

      These tests are very different, and serve the same purpose. We recommend checking with the university of your choice to see if they prefer the paper-based or digital TestAS, then plan your preparation based on that. I personally find the digital test better as it has more difficult sections. Assuming one has time to prepare, one can have an edge compared to other test-takers, so to say. (The grading is based on a curve.)

      Below please find the links to our core test of the paper-based exam:

      For a subject module, I am pasting below the link to our Natural Science subject module book.

      For the digital test, here is the link to our medicine module.
