Theorema is a prep service specifically aimed at the mathematics entrance exam for German Studienkolleg programs. It originally offered online group classes, a learning app, and on-demand one-on-one tutoring. The page clearly states that its online courses and learning app are currently paused, and that any restart date will be announced later. As such, it is better used as a reference for understanding its course structure and exam-prep approach, rather than as a product that can be reliably purchased right now.
The course scope is highly focused: it covers only the mathematics entrance exam for Studienkolleg, including secondary-school math topics such as algebra, analysis, geometry, functions, equations, inequalities, exponentials and logarithms, trigonometry, and derivatives. A notable feature is that students can choose their target Studienkolleg, after which the system matches them with a course plan and an app-based learning path. The format includes an 8-week online course with 16 sessions of 90 minutes each; the app supports learning through short videos, text, multiple-choice questions, exercises, and 15β30 minute topic tests. On-demand one-on-one tutoring is also available. The app claims to include more than 1,000 questions with complete step-by-step solutions, which is useful for timed exam practice.
The pricing listed on the page is fairly clear: the online course costs 340β¬ and includes the app; the standalone app costs 39β¬ for 6 months; and the one-on-one option consists of the 39β¬ app fee plus 49β¬/hour. The first four topics can be tested for free. The page does not mention certificates, official accreditation, a refund policy, or payment methods, so it should not be considered an accredited course that provides certification.
The organization says it has run 20 related prep courses since 2016. Both course leads have backgrounds in mathematics and teacher training. Joachim Siegert also teaches mathematics and computer science at German universities and has been involved in online test development; Christian Suttner has a background in mathematics and physics education as well as experience with intensive high-school graduation exam prep courses. It is suitable for students with a clear goal of taking a German Studienkolleg mathematics entrance exam, and who are able to learn mathematical terminology and solution explanations in German.
Its strengths are precise positioning, learning paths matched to target institutions, a large volume of exercises, and complete solution processes. Its drawbacks are that the service is currently paused and that it covers only mathematics, not a full-subject entrance-exam preparation package. Although the teaching language is not directly stated, the website and content are in German, so a foundation in German is required. There is no textual basis for judging whether access from mainland China is smooth, whether payments work reliably, or whether domestic Chinese bank cards, Alipay, or WeChat Pay are supported; these remain unknown. Alternatives include official Studienkolleg sample questions, self-study textbooks, German online tutors, or other entrance-exam prep courses.
