Dear Chini, 

Almost everywhere around the country, you will be required to deposit only one-year course fee, not that of entire course i.e. for 5.5 years. However, some colleges do give an option of paying for some years cumulatively, thereby offering a certain percentage of discounts. But, it is only offered as an option. Generally, no college around the country (private or government) will ask you to deposit the complete course fee. 

Hope it clears. 

All the best!
