What NeoJaz says. I'd rather use an HDD enclosure on USB3 though. I know you can get those for 25EUR around here while what NeoJaz recommends is about 18-ish from a quick google. You can even have a new external HDD should you buy that enclosure. lol
Either way, try running a linux distro like PartedMagic with the failed HDD hooked up to your system. If it does not detect there chances are you'll need special inaccessible hardware to read the HDD. The distro will run from an USB stick and RAM.
Also, school tasks ALWAYS go on stuff like Dropbox or Google Drive. NO EXCEPTIONS.
