15 years old with a back problem? Should I take Dahn Yoga?

Question: Hey, I'm 15 with scoliosis and have very bad posture.(I slouch/bend forward all the time) And just recently my lower back is starting to get sore. Especially when I bend down and come back up, my lower back will be uncomfortable.
And I'm 15 with a elderly back problem.
Would Dahn Yoga help? I heard a lot of bad things about it though, but it is the only "yoga" center I can go to so its either this or nothing.I probably won't get caught in their schemes since I'm only 15 and I look around 12.
Would it help my back? And how much does it cost?
Thanks in advance!
