I think it is better to ask for help from professional essay editors as they know their work and will give the best pieces of advice. I know this from my own experience, I used to ask my friends to help me, but they couldn't all the time explain my mistakes. However, since I started to work with an editor, I began to understand the way I should write an essay and now I write them much quicker than I used to. Also, now it is easier for me to write one without making mistakes. I hope that I helped you.
