Have friends proofread
Keep in mind, though, that probably none of your friends are that much better at it than you are. I did the same for my bachelor's and master's thesis.
In the end, I regretted it bitterly, because despite multiple proofreading loops, so many mistakes crept in that I was asked about them by https://editius.com/resume-formatting-service/ or examiner. This was not only incredibly embarrassing, but also had a negative impact on the evaluation of my master's thesis. Therefore, next time I would definitely seek the help of professional proofreaders and have a scientific proofreading done instead of bothering my friends with it.
Proofreading vs. editing
Once you've decided to enlist the professional help of a proofreader, you need to look into the different services a proofreading service can offer. After all, not every student needs an all-round check for their work. If you don't want to spend a lot of money unnecessarily, you should know exactly what kind of support you actually need. That's why I've taken a closer look at the different proofreading services like https://editius.com/paper-corrector/ and summarized for you what the difference between editing and proofreading actually is.
Proofreading by a professional
A professional proofreading service is primarily concerned with uncovering gross formal errors in your thesis. Proofreading therefore focuses on spelling, punctuation and grammar in your work. In plain language, this means that the proofreader checks your work for spelling mistakes with https://editius.com/essay-proofreading/, adds or deletes commas and other punctuation marks, and makes sure that your work is also grammatically correct. These basic corrections help to show your examiner that you are capable of professional writing. Because, as you probably know, no one likes to read a text that is riddled with grammar and spelling mistakes. Having your bachelor thesis proofread is therefore recommended for all those for whom punctuation and spelling is a closed book.
