i forgot my passcode to my ipad i need for online school in a week and dont have a apple computer at home and need to reconnect it to itunes. what in the world do i do?!?!

If your iPad is disabled, or you have forgotten your iPad passcode, you’ll need to follow this process:

If you’ve forgotten the passcode on your iPad, or your iPad is disabled – Apple Support

You’ll need access to either a PC (with iTunes installed) or a Mac (with iTunes or Finder - as appropriate for the installed version of MacOS). Use of a PC/Mac is unavoidable, but the computer doesn’t have to be your own - that of a helpful friend or family member will suffice. Alternatively, the technicians at the Genius Bar of your local Apple Store will be delighted to assist.

You’ll also need your AppleID and associated password. If these have also been forgotten, they can be recovered here:

To recover your credentials, you’ll need access to one of the following:

• Your primary email address mailbox that corresponds with your AppleID
• Any of the secondary/recovery email addresses that should be configured for your AppleID account
• Any of the trusted telephone numbers (fixed line or Cellular/Mobile) that are associated with your AppleID

Unless you AppleID account has not been fully/correctly configured, or has been seriously neglected, recovery of the AppleID and password should not be difficult.

More information about recovery of your AppleID:

When you recover access to your credentials, you would be well advised to log-in to your AppleID account from a web browser - and verify/update any email addresses and trusted telephone numbers:

It doesn't need to be an Apple computer; you can use a Windows computer that has iTunes installed. See instructions in If you forgot the passcode on your iPad, or your iPad is disabled - Apple Support including the following from that link:

You need a computer to follow these steps. If you don't have a computer, borrow one from a friend, or go to an Apple Retail Store or Apple Authorized Service Provider.

You don’t need to use an Apple computer. You can use a machine running Windows and download iTunes for that machine. All you need is to have iTunes (the newest version) installed on your computer and when you connect it iTunes will take care of what you need to get your device reset so you can get back into it.
