SOP is very serious letter, give your all time to it. you should follow these steps
1. google for SOP
2. find sample SOPs
3 read many sops and write 5 or 6 drafts for your sop
4. make a final draft
5 share it here on forum
6 we will edit your mistakes and you will have your final sop
if you take someone's SOP and dont write your own sop then VO will catch it easily because language, grammar, words, etc all should match your profile.
