Things every student should keep in mind
- Free example essays found anywhere online are available to anyone, which makes them used, re-used, paraphrased, and abused millions of times.
- Watch out, some are poorly written!
- We strongly discourage you to submit free essays or any of their parts for credit at your school -- they are easily detected by PLAGIARISM CHECKERS.
- Get a brand-new, 100% original paper that will be written especially for you following YOUR EXACT instructions.
100% money back, no questions asked if you paper is plagiarized (this won't happen anyway).
We use a simple but effective principle: one satisfied customer will come back for more, but one who was cheated and misled will tell 10 others too.
Our clients are treated with the highest level of respect that a legitimate student deserves. You, as a customer, will feel this attitude starting from your first contact with our essay service and all the way through.
A significant percentage of cheap essay writing services have also been the source of complaints from students for selling cut and pasted work off the net -- this is a world away from the personalized essay service that EssayPride offers. All our guarantees are always kept -- we are nothing without quality, affordable prices, and the high degree of customer satisfaction!

I am an ESL student and I am only learning how to write good papers in English. Thanks to EssayPride I am mastering this skill much faster. They help me because they always respond any questions and explain me things I do not understand. They also strictly follow the deadlines and I am never late with my assignments. Thank you very much, guys, your hard work is appreciated. I will surely be ordering more.

Oh my Gosh! My life has become sooo much easier after I've come across this website. I am a working student, so sometimes I am too overwhelmed with so many things and I really need a hand with my papers. I am glad I have found a company I can trust. I have confidence in these guys, because they proved to be good quite a few times.

I never leave reviews for products or services because I am quite particular and picky. Surprisingly enough, EssayPride has managed to satisfy all of my requirements, even though I asked for several alterations to the paper they've sent initially. My assignments are quite complicated and it is essential to possess a certain level of knowledge in order to write a decent paper. These guys have managed, so I give them four stars.

I am a Korean student studying in the US. I would like to thank essaypride staff, especially writer Jeff P., for helping me out so much. My grades are good with all your help and I keep calm about the results of my year.

As probably any student, I was quite hesitant about asking somebody else to do my assignments at first. However, after EssayPride has sent me my first paper and I've read it, I understood that I could actually learn a lot from them. The research they've done was impressive and I understood the topic even better than after going to class and reading my textbook. I am not using this website to "cheat", I am using it as a tutoring service, they help me to understand the material better.
