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 Pedro Seixas

FEP - Business

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!

Sophia Mizinski

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.
