on a grant?

Would you please tell me the meaning of the phrase “on a grant” in the following sentence!

I finished high school with a grade point average of 3.5. I went to college for 2 years on a grant with plans to go to medical school.

It means that some institution (such as the government, or some foundation or charity) gave him money so that he could go to college.

Thank you very much, Dozy!!!
