TOEFL - to take or not to take

TOEFEL is required by many institutes especially in the US. But since I am yet note sure about applying to any US school in this round, I am not sure about taking toefl either. Frankly speaking, its a waste of money. I do believe I have good command on the English language. Though while speaking, I might sound like I am not that natural, and speak with an Asian accent (whatever that is). I still think I need not take the test just to prove my comm skills. Let the interviews bekon, and I will talk my way through.

Also, I dont think many institutues are strict about TOEFEL. I think many of them give waivers to students who have completed their degree course from a college where mode of instruction was English. Here is the mail which I got from adcom from Oxford:

"To apply for an exemption to the TOEFL test, plesae address a letter to the Admissions Committee, stating the reasons why you feel you do not need to sit the TOEFL test. Please then upload this letter to the TOEFL section of the application form. The Admissions Committee will then make a decision on this letter."

I do believe this could be decided on case to case basis, and depend on the school one is applying to. For those who want to apply for a waiver I would suggest to write a strong argument on why you do not need toefel. Like if you have worked in MNCs, international exp (small or large), debates won, toastmasters club or anything of that sorts.
Also, if they still think your application is strong and your toefel is below par, they may ask you to retake before giving a final admit. I am not sure about this though, but a few schools do it like this.

I would suggest work hard on your essays and your overall application, and low score in toefel or lack thereof would be nulified. Like the way I am doing.

Have edited the essays for the hundredth time now. The first draft was ready on 31st august, and its more than one month now that I am tweaking it. I think after a while one should stop looking at the essays and just submit them. Gosh ! Wish it were a bit easy.
