Helpful learning platforms
OMB+
✋ Recommendation: "OMB" stands for "Online Maths Bridge Course" and offers a lot of free content to make the transition from school to universityschoolmathsmaths easier through repetition and practice. The content is permanently available. Tutors offer daily support in the call centre. The course helps you to work through the school maths material so that you can then follow the university courses without any problems. The course is divided into individual chapters.
Max Academy
Students from Cologne have developed a learning platform that offers a good opportunity to practise for written exams. You can solve exercises, have the solution displayed step by step and also repeat the underlying theory there.
Please note: Some of the content presented contains minor inconsistencies or deviations from the procedures we are familiar with. In addition, it is mainly tasks based on fixed schemes that are trained here, but not those for finding creative solutions.

This website contains links to videos on standard topics in "Higher Mathematics". The 5 to 10-minute videos each highlight one aspect of a topic; some videos often belong together thematically or build on each other. Many videos end with a final task, the solution of which is included in another video.
Further links
Here is another collection of links that Prof Grieser has put together that might be of interest to maths students. The video series by 3Blue1Brown in particular provide many useful intuitions. It should be noted that they often do not go into the formal aspects, which is also very important in the degree programme.
