In regards to documentation, you MUST put in your latest Year 12 report (I'm assuming you're a high school leaver like me) at least. If you're doing scholarships regarding leaderships, you need to put in scans of documentation that prove you've been doing whatever you claim to be doing (so I have a senior profile that my school culminated for me that listed every single leadership & charity/fundraising I've done etc). I also threw in scans of my certificates for every academic achievement (in Year 11/12, since its more relevant than Year 7 for example).
