"Mrs. Ruwani Kannangara was my chemistry tutor for the GCE Advanced Level examination (VCE equivalent), in Sri Lanka, which is an extremely competitive examination as only less than 8% of the candidates get admission to the state universities every year. Mrs. Kannangara was an excellent tutor who carefully guided and inspired me to achieve much more than I believed I could. Under her guidance, I got the highest attainable grade (A) for chemistry in the GCE AL exam, which helped me to enter the best engineering faculty in Sri Lanka. She was an exceptionally dedicated tutor and a mentor whose guidance and inspiration are still driving my success as a current Ph.D. student pursuing studies in the area of Nanoplasmonics. I highly recommend Mrs. Kannangara as an amazing teacher, without any reservations."
