Is it normal to feel lost after starting in architecture school ?

It’s been 3 weeks since i got into an architecture school. I am doing fine in everything except design studio 1. It is bothering me that i can’t understand the concepts, i can’t think much of new designs. But i am doing fine in making things if given all the instructions and in design communication sketches.

I kind of feeling scared if i will not be able to think like an architect or be an architect by what i am experiencing now. Specially when i didn’t really planned on studying architecture.

I want to know that is it normal to feel lost and hopeless in semester 1? Or am i not suitable for it?
