Dear applicant yes, being a B.Sc Science candidate also you can apply for Event Management course, as the eligibility of this course is your 10+2 degree in any relevant stream froma recognised university. Diploma in Event Management is a one year course to pursue, but after diploma you need to enroll yourself into BBA in Event Management course followed by taking admission into MBA degree if you want to. The more experience along with knowledge that you gather the better is your selection possibilities.

Hope it helps!!!
