GRE and OGS statement of intetrest

[nightmarerideson]

So a couple of different issues are the anxiety of the hour for me. IF any one can offer advice in writing a statement of interest I would really appreciate it. Also, I am considering rewriting the GRE soon but am very nervous about the possibility of doing more poorly or not much better than the first time around. I believe even an increase in my scores may not appear much better than just playing it off like a bad day. Unless I somehow find the time to make it a huge increase, which I fear I will have difficulty with. I get major test anxiety. Any words of wisdom on either of these concerns?
