hi there varun.....
i think u shud take a proper transfer so that in case any day u want to reregister than ur present articleship would b counted. also ur principal would not let his seat occupied for no reasons.... the exact form can be found from the insti.
Also 1 sugession.....in case u r not satisfied with a articleship, choose a different field al together like say project consultancy or investment banking.....they to take in industrial trainees...... dont leave the entire cource just coz u r boared of it....
