Dear PhramacyStudent2001,
In Marietta Atlanta, there are only 4 seats for the TSE as per a friend who appered for the TOEFL there. So the chance to get a seat there is very less. But in LA there are so many seats that some of them to get cancelled is very high. So do not miss the opportunity. I appered for the TSE in Sandiego, CA and there were only five seats. So jump in wherever you find a seat available. Good Luck!
Hope it helps.
Thanks!
