Have you done any special study or research work? If so, fill-in the details. This is a good place to elaborate on any experience that you have that is particularly relevant to the job you are applying for. For example, did you work as a summer intern doing work similar to what you are applying for or work in the same field you are applying for? Have you worked on research projects that are related to the job you are applying for?
Have you had special training that would make you better qualified for the job you are applying for? For example, do you have special training in how to use equipment or instruments that would be useful in the job that you are applying for? Have you had night classes in technical writing or speech?
Do you have any special skills other than what you learned in the course of your schooling? For example, do you speak a foreign language?
Note, the above are just examples since I don't know anything about your background or the type of job you are applying for. The questions give you an opportunity to stand out from the crowd by highlighting additional capabilities that you can bring to the job that the average applicant might not. Make sure to put down anything that might remotely give you an edge. Applying for a job is a very competitive process.
Hope these answers have been helpful. Good luck with your job search!
