Gaining proficiency in KISSsoft requires dedicated study, but the ecosystem is rich with learning materials.
Developed by in Bubikon, Switzerland, KISSsoft is a modular calculation program for the design, optimization, and verification of machine elements according to international standards. While it is best known for its unparalleled capability in gear design, its scope extends to shafts, bearings, shaft-hub connections, springs, belts, chains, and complete gearbox systems.
If you are interested in exploring similar engineering design software for your studies, I can also look into academic licensing for alternatives like ANSYS or SolidWorks.
