I am a Molecular biology graduate, aspiring to do my doctoral study in U.S. Currently I am applying for several graduate programs. So far, my statement of purpose (SOP) mentions about my academic and research activities conducted till date. Should I mention about extra-curricular activities like playing badminton, active volunteer (weekend art classes) in an orphanage, etc.? Or I should be just professional by not adding the above stated activities.
I am confused of varied responses when I surfed internet for SOP templates. To be precise, I want to know whether adding extra-curricular activities in Grad school applications will boost my admission or not??
