What they fail to realize is that this fight is not a fight for myself, it is a fight for others. Yes...... it is not a fight for me as I do not have plans to ever school in Nigeria neither will my children. Your children may school in Nigeria and they might be unfortunate to be a victim of circumstance by a lecturer someday.
AppleCare (not AppleCare+) doesn't cover accidental damage, such as cracked screens on iPhone, iPad, etc, and usually for devices that are not covered by AppleCare+, regardless if they are covered by AppleCare, they are subject to non-AppleCare+ fees to replace the screen.
There are independent iPad repair services that may be able to replace the screen for less. Do a web search for ipad repair. You can also look for parts and instructions and do the repair yourself. Note, though, that if you elect to have the iPad serviced by an unauthorized shop or perform your own repair, you will get no further support from Apple.
