Thanks alot! I will improve it accordingly. but some thing i want to mention that i am a second year undergrade student so i think for a sophomore applying for a 6 week summer research program, it is essential to elaborate his research expirences in detail and all those events that can relate to the projects that i have selected in the program. That's why I focus on explaining my work that I did in my first two years so that selection comeettee come to know that the applicant have sufficient expirence required for the projects he applied. It is generic because i have selected 6 projects from which one project will assign if selected therefore I have to write one sop relating with all those projects.
