Dr. Sahan is a qualified teacher and I can highly recommend him.
Good tutor that accommodates individualistic needs. Her way of teaching is suited to maximising your knowledge of the subject, and reaching your own maximal potential. Is usually able to manage her teaching plan according to what benefits you the most. Greatly helped me and gave me the much needed boost with regards to this subject. Would highly reccomend to anyone thats sick of sitting in massive classes and listening to someone that has little to no idea about how you study.
