As the title says, will I have to do RD??
Apparently you have two weeks for your recommendation letters to come in after November 1st… I don’t know if this is true or not because it says November 1st on the application.
I’m really worried now, I don’t want to have to do RD 
MIT’s latest newsletter reads as follows:
Late Materials
The deadline for EA applications is November 1, but your school/teachers may submit their materials after the deadline. We are much more flexible and understanding with schools and teachers regarding deadlines.
Chill out and sit tight for the next month 
Best of luck!
