We have included a list of these errors in the latter part of the booklet. Additionally, a good PS should range between 600 words, unless otherwise specified. There is strictly no limit in terms of paragraph count, but a good rule of thumb is to have between six to eight paragraphs.
Once you have produced an essay by going through the steps enumerated above, you can improve it further by going through this last section for added measure. These will help you check for final errors.
