question about simple sentences using until

I have very simple sentences below.. but for some reason I'm still having doubts if they're correct.. I think it may be because I don't have so much experience writing these kind of sentences (use of until for the past).. can someone just confirm if they're correct? and if there are alternatives.

Until senior high school, I didn't like to study.

Thanks in advance.
