Nets it formed to make shapes. I cannot help to explain as it it hard, you have to form the nets into shapes in the mind.

You can try cutting out different types of nets to fold and play around with them.
I teach my students using a rubix cube, with it, they can visualise better.

Think cutting out the shapes is a good way to see the shapes.

You cut them out and practise using the models, which should train your eye to 'see' them in the exam.

I think once you have trained your eye to 'see', it works both ways folding as well as unfolding. I know some people find this topic harder than others (I'm one of them, but my daughter finds it easy), but it can improve with practice.
