SOP/RECO/Resume

You will have too many things to write in SOP, but SOP should be small.
Here is what u can do:
1) although its not an requirement... they expect a resume. so do make a one page resume.
so that SOP remains SOP and resume remains resume
2)you will not have space to include much technical details in SOP/REsume..
so the things you CANNOT include in SOP/resume, let the reco letter include it.
For example.
you did project A under prof Sharma.
So let prof sharma write all the technical details in the reco latter..

The gist is .. let SOP/Resume and Reco letters complement one another.
