My teacher asked to revise my report for grammar mistakes and spelling. It's a lab report, not a dissertation, but ok, I ordered it here to see, perhaps, you'd have better luck than me. To see what I was paying for, I asked to turn on the mode of tracking changes. I think my expert deserved more money for all those changes she made. OMG! I even left some tip for her to express my gratitude! Nice!
Thank you, Albert!
