This semester is very slow, compared with the rest of the school year.
This is being a nice slow semester, with little academic work!
This semester is a cake, I am taking just some credits (Maths, English, Biology...)
This semester is being light, I am taking just too subjects, seemingly easy! Quantum mechanics (a.k.a. Quantum physics) and Quantum Chemistry!
This semester is really light, the number of credit hours will be the lowest ever!
And other ways...
