Hi neha,

            We advice you to complete SSLC first and then start preparing for Entrance exams.

Admission to interior design courses will be based on the aggregate score obtained in qualifying examination and entrance tests like Symbiosis Entrance Test (SET), India Entrance Examination for Design (AIEED) etc. 

Hence you have to obtain very good Marks and rank in above mentioned examinations to get admission in best designing colleges.

All the best
