For the next semester, Mileva returned to Zürich, where she finished her studies in 1900, but without getting a degree, because her professor only gave her a 5 (out of 12 as the best possible mark) as a mark in the final exam. However, she wasn't matriculated as a regular student there, because female students were only admitted in 1900. In the third semester she studied in Heidelberg.

She was the only female student in her year, and one of her colleagues was Albert Einstein (1879-1955). In Fall 1896 she switched to the Eidgenössische polytechnische Schule (today ETH Zürich) to start her physics studies. She then finished her school education in 1896 in Bern and started her studies in Zürich, where she first studied medicine. In 1894, her father registered Mileva in Zurich in the Höhere Töchterschule. When the family moved to Zagreb, Mileva wasn't allowed to go to high school as a 'normal' pupil, but had to be registered as 'private pupil'. To attend high school classes, she had to go to school in Šabac, which belonged during that time to the Kingdom of Serbia. Mileva was a very good pupil, regardless of numerous school changes during that time. Her mother tongue was Serbian, but in her neighborhood she also learned German and Hungarian. Mileva Marić was born as third of five children to Miloš Marić (1846-1922) and Marija (Ružić) Marić (1846-1935) in the house of her maternal grandparents in Titel, which belonged at that time to the Austrian-Hungarian Empire.
