Cracked screen iPad and apple service center

Screen damage - including cracks or breakage - is generally not covered by the Apple's limited warranty. As such, your only option will be to finance replacement of the screen assembly.

For practical purposes, in lieu of repairing and returning your own iPad, Apple usually exchange the iPad for a renewed/refurbished iPad of the same model and specification. The cost of the exchange is the same as would otherwise be charged for repair. Unless you have benefit of an active AppleCare plan, an out-of-warranty repair while expensive will be somewhat less than the cost of a replacement iPad.

As for out-of-warranty repair costs, Apple offers a fixed-price price repair. You can verify eligibility and cost for your region/country here:

If you have an active AppleCare+ plan, the cost of repair is reduced to a small excess/deductible fee.

This is a user-to-user forum. No one here can give you a definitive answer about what Apple will or won't do. However, as I understand it, Apple doesn't repair iPads, they always replace them.

A cracked screen wouldn't be covered under the regular warranty.
