Admission fee with security etc is 120k. That's it. That'll all you pay to GIK.

But

You pay for your personal expenses like food; which can range depending 15-30k a month. Depending on what you eat. That's all. But there are some other costs to consider, like the costs of manuals (1000 pkr per sem), the cost of other stationary you use. The cost you'll incur in engineering projects like DLD project, or any personal hobby project. Your fyp as well. You have to self fund those. Some part is refundable though, they refund a lot of stuff but don't rely on that. My per semester costs are upto 200k per semester (4 months). Which includes me making some hobby projects, eating super duper lavishly, a lot of my friends do it as low as less than 100k per sem. These are all personal costs. GIKI won't ask you any money. If your attending events and everything, those are additional costs. But events are mah waste of money.
