Are my cholesterol levels ok?

Just had my yearly physical. My bad cholesterol was 117 and good cholesterol was 35. My doctor sent my results to me in a letter and she didn’t want to see me again, so I guess everything is good, all my other results were normal. When I read online about cholesterol levels, my bad cholesterol is in the healthy range, but I read that the good cholesterol should be 60+????? Is that right? If so, how do I raise it?
