Which health insurance is best for students?

I am looking for health insurance companies, most of them are not even clear and i doubt to choose. I am international student, so i wanted to ask for your opinions. -I heard about public one . That seems expensive, but if i choose private they say it is impossible to turn in public one. I also saw some that say private is problematic for low income and future, which makes me doubt more. -I want to apply one very fast, which will be ready a couple of days before application. - I saw one, which is “mariwa” it was cheap but saw no good comments

Do you have any suggestion? If there is anyone who bought as an international student, i will be very happy by your helps!
