Is my project too difficult?

Is it possible for a complete beginner to create an OS from scratch within the time of a semester?

Your OS can be as simple as you want it to be. Even just printing out a single sentence is already an OS. 

Depending on the features you are planning to implement, this project can be a daily, weekly, monthly, yearly or decades long project :)
