Is it possible to transfer contacts from PC to iPad Mini, and if it is, how do I go about doing it?
1. sync via iTunes
2. Sync via iCloud.
The first requires you have a reasonably up to date version of iTunes which you can download for free from Apple's site under the iTunes tag.
The second requires you have to an iCloud account (which really just means having an Apple ID and can be the same one you use to download apps etc and logging that in under the iCloud settings on your iPad Mini) and having the iCloud Control Panel on your PC. You can download it by searching the download section of the Support tab on Apple's site.
