Is it possible to attend CS courses and conduct research in Courant while a student at Tandon?

Hey there,
I applied for the NYU GSAS MS CS program and got rejected, but I have been admitted to the NYU Tandon School of Engineering. I had some questions that I hope somebody can answer.

  1. I wanted to know if, while attending Tandon, I can get some opportunities to attend classes in machine learning at Courant, and maybe contribute to the research being done by the professors at NYU Courant.
  2. Also, I would like to know if there is any protocol or chance that I can shift from Tandon to Courant.

Any help would be appreciated :).
Regards,
