Trending @Infosys; Reason to get release from the project.

I have 5+ years of experience at Infosys. And now it's high time for me to make a switch. However, I am currently swamped with heavy work on a project. Due to this, I am not able to study for my switch. Therefore, I plan to get a release. Can you all recommend a good, valid, and equally genuine reason that will be convincing to the manager without affecting my performance rating? #release #infosys #worklife
