Need help with SOP. Should I include my details of my academic performance

Hello, I am currently in the process of writing my SOP for a Masters program in Electronics and Communication but I have a doubt.

Since I will be sending in my CV/Resume to all the universities I am applying to (I believe this is what most people do or am I wrong?), should I include details of my academic performance, such as my percentages in the different modules I have studied or details of the different projects I have worked on, since those details will already be included in my CV. Is it redundant?

Also, could somebody also tell what the average length of an SOP is?

In my opinion, these elements should all be included. Most schools have a limit on SOPs, but, 2-4 pages or 1000-1500 words ought to do it.

I would highly recommend Don Asher's book on Graduate Admission Essays for some good examples and ideas for getting started.

Hello,

You should certainly include details of your past projects and future plans. Writing about your grades in a SOP shouldn't be done unless your grades were bad or below average and you are trying to explain them away. A statement of Purpose is designed to provide the reader with a deeper insight as to why you would be a great fit for the program and what you hope to do once you have completed the degree. Your grades will already be reflected in transcripts and on your resume. Including it again in your SOP is not a wise use of space and might appear as though you are bragging. -AAO

Hi,
I think you should not include all details about academic performance.You should only mention your past project and present experience. If you are among top 5 or top 10 in your undergraduate study, then you may include it. But If your score is low then you shouldn't mention that.
