Why dont you just do a search at Yahoo or go to PSB Academy website. All the info that you need including course fees is reflected there.
As for sharing a rented apartment, it really depends how many people you are sharing with.
You usually have to pay a 1 month deposit of the rent.If you get it through a housing agent ,then you have to pay the agent 50% of the rent,,i Mean 50% of a month.
If you are taking a 3 room flat for rent,depending on the area..the rent is usually $700-$800.
But if you take a room for yourself, a normal room without aircon,you can get it at $300.
Hope all the above info helps you.
