You can’t see the wood for the trees…?
Students, has your superviser recommended that you get your work checked over by a proofreader? Rest assured, your spelling, punctuation, grammar and context will be checked thoroughly by me. I will raise queries if the sense is wrong. However, as the student you will take responsibility for the changes you want to make.
Please note, I do not edit or improve the structure of the writing if it is not grammatically incorrect. That issue strays into ethical territory.
