The school where I learned 4 years ago wanted air law and medical before solo.
Medical may be for insurance,air law so you understand basic rules of the air.
Sensible to get medical done asap in case you find out you can't fly.
Air law one of 7 exams, so it pays to get cracking on those as well.
I concentrated on one exam after another until they were all done,but must say,studying at 60+ was not as easy as 16!
Good luck.
