A new study format, much more dynamic and easy to learn. Hollow helped me to understand subjects that, with FEP classes alone, I would not be able to. I would say it is a salvation for students!

João Seixas

FEP - Business

Hollow made me enjoy accounting. The videos and exercises taught me the subject in a less tedious way, and I finally understood the meaning of it. Without Hollow, I wouldn't have achieved my desired grade in CRF (17). I genuinely thank Hollow for that.

Marcelo Garcia

FEP - Economics

Hollow's videos managed to help me get a grade that I had never gotten at FEP before. For the first time, and because of the Hollow, I got a 20 in Mathematics I.

Adriano Fructuoso

FEP - Business

Hollow was my greatest ally throughout the courses of Statistics I and II! The videos were completely engaging and provided me with a quick and effective understanding of the content, which I initially had no hope of comprehending. Hollow gave me the tools to face exams with confidence and ease. I feel immense satisfaction in finding a platform that provides me with this support outside the classroom!

Bianca Mendes

Universidade de Coimbra - Psychology

The Thermodynamics 1 course is truly impeccable!! The exercises solved in a detailed and well-explained manner have given me the foundation and confidence to take the exam.

Victor Melo

FEUP - Mechanical Engineering

Hollow helped me a lot to understand the subjects! It offers quick and practical classes that greatly complemented the college subjects and made all the difference!

Leonardo Ludgerio

FEP - Economics

Hollow was a lifeline for Statistics I! The dynamic videos made me understand the material much faster and, therefore, be able to take the exam more easily. I'm very grateful!
