IMPORTANT:A number of schools do not require you to send your official score reports of the GMAT and the TOEFL during your application process. You are only required to send the official score reports (that is, get the testing agency to send official score reports on behalf of you) if you are admitted. Official reports are required only as part of the post-admission verification process.
I'm realizing this only now. Had I known this before I took my GMAT and TOEFL I would not have chosen to send my score reports to the schools I did. Turns out that these schools require score reports only once you are granted admission. Instead I could have sent it to schools that require the official reports before the application (although I haven't searched and found out which schools require this).
Did anyone use this technique?
Edit: I'll post a list of schools (as I do my research) here that require/do not require official score reports before the application deadline.
Does not need Official Score reports of GMAT/TOEFL before deadlineLBS - not required before deadline but required before decision
UCLA Anderson - not required before deadline but required before decision
Requires Official Score reports before deadlineFuqua (Duke)
Kellogg (updated 2023)
IE - since no deadlines the official reports should be submitted along with app
Please let me know in the comments about schools you have come across that require/do not require score reports. I'll add them to this list. You should be absolutely certain of the info, either by way of correspondence with the admissions committee or if it is explicitly stated on the website.
