Hi RA12345, and welcome.
As Tdol has rightly pointed out above, we do not and cannot write essays on anyone's behalf. You need to write your own essay and submit it to your teacher to be marked. After you get it back from your teacher, you're welcome to post it to our Editing and Writing Topics forum along with your teacher's comments.
That's OK. However, the forum rules (which you have accepted) show that we cannot help with homework or assignments. Your teacher wants to see what you can do on your own. Your teacher is not interested in reading an essay that was written by all of us!!
You must submit your essay to your teacher and then, when you get it back, you can come back to us if there are any comments or corrections from your teacher which you don't understand.
Hey. I need to write an essay, the topic is Science & Technology. I was advised to ask for help from essays writers specialists of link deleted by moderator. I just never bought it, so I need your advice. Is it better to write by myself? If so, how to start?
