**SYLLABI**

(ENGG/MEDICAL/BDS/ARCHITECTURE/PHARMACY)

The Syllabi given hereunder for OJEE-2011 are only illustrative and not exhaustive. The syllabi are in line with courses of studies in Science stream for the Higher Secondary Examination 2011 of CHSE, Orissa. Since JEE is conducted with a view to preparing merit lists for admission the decision of the JEE Committee as regards the scope of the syllabus is FINAL.
