Can you proofread this for me please?

Mr. Johns has demonstrated some very unique findings about physical therapy through different research and projects. Michael has developed a seminar curriculum and has done many clinical assignments at different locations. He has presented his findings to different universities and has been recognized for such great academic achievement. Mr. Johns presentations have been ranked the best in the department of science. While in my class, Michael always scored the highest grades on all of my examinations. His services have benefited other students in his classes and has helped others become interested in becoming physical therapists.

That sounds very good with one exception. You have used the word "different" in three separate places. I would say "several universities" , and "through both research and varied projects."
