Hi aspirant,

Bcom Hons and Bcom Corporate Secretaryship are both a three year course provided by the universities. But Bcom Hons is a general course that does not speacilizies in any particular subject, whereas Bcom Corporate Secretaryship speacilizies in the subjects of company secretary. Now this may help you in getting a more thorough knowledge about the Company Secretary course provided by the ICSI.

Hope it helps!
