Is levoscoliosis curable?

Last year I took the entrance exam to the military and underwent complete medical test. After a couple of months I learned that I didn't pass. Now they have sent me a letter telling me that I was diagnosed with LEVOSCOLIOSIS W/ GRADE 1 ROTATION. What does this mean? All I know is that scoliosis is if you have S-shaped spine and levo- means toward the left. Is my condition tractable? I never knew I had it. Is there possibility that I could still join the military if I got this cured?
