Never too early! Just depends if its in person whether a companies insurance will cover it. I had my first placements at end of yr 10 and really helped me decide my future. Emails, phone calls and possibly even visiting in person, making use of any family friends or friends of friends to try get placements will help. I also know medic mentor, its mostly for medics vets and dentists, but has a society for law now. They have weekly online meetings and other benefits, all free and deffo worth looking into. Good luck!!
