The grading of academic papers is influenced by many external factors over which we do not have direct control. Hence it would be unprofessional to guarantee clients a certain grade. What we can promise is a paper that lives up to the highest academic standards and meets your expectations. This is guaranteed by our ProQualitas assurance. If your author fails to deliver the expected quality, we will apply corrections for free — or you will get your money back. Therefore Contact us within three months of the completion date.
