How to get the most out of your experience with Homework Writing Services
One writer throughout the entire course
If you like the writer, you can hire them again. Just copy & paste their ID on the order form ("Preferred Writer's ID" field). This way, your vocabulary will be uniform, and the writer will be aware of your needs.
The same paper from different writers
You can order essay or any other work from two different writers to choose the best one or give another version to a friend. This can be done through the add-on "Same paper from another writer."
Copy of sources used by the writer
Our college essay writers work with ScienceDirect and other databases. They can send you articles or materials used in PDF or through screenshots. Just tick the "Copy of sources" field on the order form.

Great job on the revision. Rating reflects the revision after upgrading the writer. Previous tutor's assistance was not very good at all. I am still very happy with the assistance provided by the tutor and the support team.

The paper was beautifully written and exceeded my expectations. John was really helpful in ensuring that the files were attached to the order when I had issues attaching them. Thank you to the tutor and John. I was really excited that I received my paper ahead of time!
