Between 1846 and 1859, Karacs managed her own school for girls in Miskolc. The school had four female teachers and the three year long curriculum included Hungarian, German, arithmetic, housekeeping and sewing. During this time Karacs supported her local community by supplying the working people of Diósgyőr with copies of revolutionary newspapers before the revolution in 1848. She also published a collection of short romantic stories in 1853. In 1865–1877, she worked as a private teacher in Budapest. Her reputation led to her being invited to be a tutor to King Louis Philippe's grandchild. However Karacs had been invited to run the school by the Calvinist church in Miskolc and she became the head of the Zrínyi Ilona Grammar School for girls until 1859.
