Fernando Alonso Bilfinger - Cofounder

After achieving 92% in Physics HL in the IB Diploma in 2017, Fernando realized that exam results depend on the quality of the study material. Thus, he decided to combine his own revision notes with the best he could find in books, websites, and papers, in order to provide all students with the tools to nail IB Physics. He designed free IB educational websites and has been working to broaden their content ever since.

André Widmann Civitareale - Cofounder

André profited from educational websites throughout his journey with the IB Diploma. With a passion for both chemistry and design, he joined Fernando with the aim of merging high-quality content with excellent layouts. He has been responsible for improving the users' experience through constant feedback and arduous study.  

Kevin Anders Sebastian Pettersson - Cofounder

Due to a strong will to share his knowledge, Kevin joined Fernando to create free content for IB Chemistry students. Equipped with a vast experience that helped him achieve a 7 in SL, he developed excellent content that includes every single aspect of the SL syllabus and has been creating the HL part as well.


Isabela Lopes - Physics Developer

As a current IB Physics HL student, Isabela wishes to achieve the best possible results and help other students do it too. Thus, developing content for has not only been helping her prepare for the exams but also been a way to spread what she learns everyday in school. 

Desirée Belga - Chemistry Developer

One "chemistry-freak," Desirée enjoys studying about every single atom, molecule, and structure that composes the world. Having (naturally) studied IB Chemistry HL, she now seeks to spread her love for Chemistry by proving other IB students with an excellent study material. 

Carol Zweig - Biology Developer

As soon as Carol found out about Fernando's initiative with IB Physics, she decided to join the team and use the knowledge she acquired whilst achieving 7 in Biology SL to create study material for biology students. She has been delving into varied sources in order to distill the most important information.


Matheus Hartschuh - Former IB Chemistry SL Student

Matheus has a natural curiosity about various subjects. Hence, nothing seemed more natural to him than to foster that curiosity in other students too. The best way he found to achieve his aim is helping to develop the websites' content and spread them to students around the globe.

Marco Koblinsky - Former IB Physics SL Student

Having been both an enthusiastic programmer and robotics teacher, Marco has been helping to improve the websites' interface. With a great knowledge about physics and webdesign, he brings refreshing ideas to the team.

Victor Rosolem - Former IB Physics HL Student

Victor thoroughly enjoys both acquiring and sharing knowledge. Giving tips to improve the website's content and design has been an important part of their development process.

Pedro Toledo - Former IB Physics HL Student

One of the website's first users, Pedro's feedback whilst a Physics HL student has been vital to improve the website. After graduating, he decided to join the team and test new features on the website.

João Rodriguez - IB Physics HL Student

João has always enjoyed learning about multiple topics within physics. As an IB student, he decided to take IB Physics HL and got in contact with this website, which prompted him to help improving its content. is a student initiative to provide free material to help international students prepare for the IB exams.
