At UNIPERFECT, our goal is to help our students find the Master’s or Ph.D. program that is the best fit for them and be admitted to the world’s top universities.
To give a few examples, our students have been accepted by the following universities in the United States and Europe:

Nikolas Papadopoulos:
- NTUA, Electrical and Computer Engineering
- Columbia University, PhD Bioengineering and Biomedical Engineering
I had a very positive experience at UNIPERFECT! What really meant a lot to me was the excellent communication I had with UNIPERFECT’s team, the interest they all showed in my needs, and their willingness to support me.
I prepared for the GRE at UNIPERFECT, and I simply can’t imagine a better Quant instructor than Avgi. What’s more, I had a great amount of help in preparing my applications by the UNIPERFECT mentors. I was in touch with them regularly and felt that they really dedicated time to helping me with my application.
Zoe Angelopoulou:
- NTUA, Architecture
- Columbia University, MSc Real Estate Development
A huge thanks to the UNIPERFECT team! Aspasia, Avgi, and Konstantinos, your help during my preparation for a postgrad was invaluable, and a big part of being admitted to Columbia was the result of your contribution.
Preparation for the GRE is expertly guided. A positive attitude, professionalism, and personalized guidance to write your personal statement are only part of what I encountered at UNIPERFECT. You were the right choice for me, and I would choose you guys again if I had to!
Christina Gasparinatou:
- NTUA, Civil Engineering
- Cornell Tech, MSc Operations Research and Information Engineering
Reliable prep center for graduate studies abroad with instructors who are not only highly qualified in their respective field, but also genuinely interested in helping each and every student. I would definitely choose UNIPERFECT for my preparation again!
Orestis Karamouzis:
- AUTH, Civil Engineering
- University of Florida, MSc Transportation Engineering
Excellent prep center for studies abroad. Professionalism and support every step of the way are the first two things that come to mind when I think of UNIPERFECT. Most important of all are the instructors and counselors’ positive vibes. In other words, guaranteed success.
Gerasimos Chatzoudis:
- NTUA, Electrical and Computer Engineering
- Rutgers University, PhD Computer Science
Excellent prep center, in more ways than one!
For starters, Avgi, who is in charge of the GRE preparation (Quant), is truly exceptional. She may well be one of the best instructors in the field, which is the main reason why I chose UNIPERFECT.
Furthermore, the entire team (Konstantinos, Aspasia) really takes care of the students. They adapt to our needs and desires and create a cozy environment – a factor that I believe is key when preparing for applications.
Finally, UNIPERFECT has invested in the mentoring/coaching of their students, which is more than necessary during the application process. From my experience, Aspasia is remarkable, a true asset of the UNIPERFECT team.
Noufris Chatzicharitou:
- NTUA, Naval Architecture and Marine Engineering
- University of Michigan, MSc Naval Architecture and Marine Engineering
- University of Washington, MSc Business Analytics
From the very first day, the instructors introduced us to learning materials, practice tests, and effective test-taking methods. The instructors are energized and experienced, and they help students assimilate what they need to know to succeed and get higher scores. Specifically, I believe that Avgi is the best GRE Quant instructor in Greece.
The environment is both professional and extremely friendly towards students. The instructors and administrators manage to reduce stress by surrounding students with positive energy.
When I was taking classes at UNIPERFECT, students had the option of a hybrid class (a compromise between a face-to-face interaction and an online class) which I found very flexible.
Personally, I would recommend UNIPERFECT for everyone who pursues graduate studies and the enriched career prospects that follow higher education. Their mentorship and guidance enabled me to pursue a Masters degree from a US Business School.
Demos Bogdanos:
- DUTH, Civil Engineering
- DUTH, MSc Geotechnical and Earthquake Engineering
- Purdue University, MSc Structural Engineering
The best prep center for studies abroad. All instructors are highly responsible and wonderful people, as well as accomplished professionals, who can help you achieve your goals. Avgi is the best at math and the GRE! During my preparation period, I also met lots of fellow students, with whom I’m still in touch now that I’m in the States.
Nikos Karouzakis:
- NTUA, Electrical and Computer Engineering
- Stanford University, MSc Management Science and Engineering
- Columbia University, MSc Computer Science
Excellent teachers with many years of experience in test prep. Very professional management. Friendly and relaxed educational space.

Nikos Karouzakis:
- NTUA, Civil Engineering
- LSE, MSc Management of Information Systems and Digital Innovation
Excellent prep center for graduate studies! Professionalism, the instructors’ many years of experience, and the study program tailored to a student’s needs are what sets UNIPERFECT apart. The above, combined with the daily support of the UNIPERFECT staff and the warm environment that they create, are a recipe for success. If I had to choose a prep center again, I wouldn’t have to think twice!
Vasilis Fragkoulis:
- NTUA, Chemical Engineering
- Delft University of Technology, MSc Sustainable Energy Technology
I am very satisfied with my experience at UNIPERFECT. More specifically, everyone showed a warm and genuine interest in me. Moreover, Avgi did a great job at preparing me for the GRE’s Quant – I literally didn’t come across anything that was unknown to me during the exam.
Giorgos Koursiounis:
- NKUA, Informatics and Telecommunications
- Delft University of Technology, MSc Computer Science
Everyone at UNIPERFECT is kind and willing to find personalized solutions for each student’s needs.
UNIPERFECT’s team has a people-centered approach, which sets this prep center apart from others with a more standardized approach.
I participated in the GRE and IELTS preparation courses. The level was very high, with specialized instructors and ample preparation material (paper tests, computer simulation tests). Avgi, the GRE’s Quant instructor, is very effective and organized.
Another important service that UNIPERFECT provides is application prep and academic counseling (CV, motivation letter, etc.). Aspasia really makes everything much easier for someone with no experience in this area.
UNIPERFECT provides the whole package for anyone interested in applying to universities abroad.
Dimitris Genossis:
- NKUA, Mathematics
- NKUA, MSc Mathematics and Computer Science
Upon first meeting with the UNIPERFECT staff, their warmth and professionalism is apparent. Initially, I was asked about my goals and future plans; after explaining the services they provide in detail, I was guided to create a personalized study experience.
I took the GRE and IELTS preparation courses.
In terms of the GRE, Avgi Tsoutsi and Pavlina Lampiri’s experience was obvious from the very beginning. Their expertise, profound knowledge of the test, methods, and tips really helped me unlock the GRE. Moreover, their willingness to answer questions, both inside and outside the classroom, was exemplary. The preparation material and simulation tests helped me get a high score, especially in the Quant section.
With regard to the IELTS, Alexandros Christodoulou, who has years of experience preparing students for this particular test, really made the experience feel like a walk in the park. With his help, I was able to achieve a high score, higher both overall and across sections compared to the requirements of the university I was applying to.
Aspasia Gotsi, the Academic and Career Counselor at UNIPERFECT, helped me craft a very good and professional CV, as well as a strong and well-structured statement of purpose that truly reflected who I am, what I have achieved so far, and why I wish to continue my academic studies.
I wouldn’t hesitate for a moment to recommend UNIPERFECT, precisely because I have gotten to know the people who work there. This is why they are the leading prep center for those who wish to study abroad. I truly thank them all!
