I study mathematics with the current physics curriculum at the Technical University of Berlin and am currently exploring the abstract phase of my studies. I received the Goethe-Zertifikat C2 GDS certificate in Reading, Writing, Listening, and Speaking directly in Berlin in January 2023. I am proficient in German, mathematics, and diagrams with a structured, analytical, and ergonomic approach. Additionally, I hold the Royal Diploma for Chess Teachers, which I obtained from the Chess Association of Berlin in July 2024. My Chess.com ratings since Bullet 2028, Blitz 2000, and Rapid 2007, with an initial score of 2125 in Bullet, demonstrate that I have a strong student (approximately 2100+) who is proficient in both. I pass the Unterricht an die Bedürfnisse der Deutschen Schüler and, mit besondeem Fokus auf Klarheit, Disziplin et strategisches Denken. All the certificates you have are ready to be used. R.J.

I am studying mathematics with a specialization in geometric structure at the Technical University of Berlin and am actually finding it in the final phase of my studies. In 2023, I received the Goethe-Zertifikat C2 GDS in lecture, text, written and oral expression in Berlin.
I studied mathematics and calculations using a structured, analytical, and results-oriented approach. Regarding exams, my current classes on Chess.com are Bullet 2028, Blitz 2000, and Rapid 2007, with a current rating of 2125 in Bullet. I remain modest in my approach but have progressed steadily, allowing me to effectively play from the beginner level up to the advanced level (approximately 2100+).
I insist on discipline, strategic reflection, and clarity, and adapt to the specific needs of the Luxembourgish elves. All my certificates are available upon request.
