I have participated in a wide variety of drawing competitions, in school and out. There was one on "Save Energy" by the concerned govt. department. One was organized by a reknowned jewellery shop "Tanishq". Another one by "FM RadioMirchi". So on.
I have given the official state government exams for showing your qualifications in drawing. The first level is "Elementary" graded exam and the next is "Intermediate". These exams are hours and hours long (4-6 hrs at a stretch). They have various components like object sketching, animal scenary, depicting festivals, human creatures etc. I secured above 95% marks in both. Look at the certificates-
