Can v write like this?

What's the need of leaving alternate lines? The purpose is not to fill pages. Just write the answers in exam in a legible handwriting.

I mean it gives some good look and I have habit of writing Big letters.. So they may collidue... And I feel invigilator can read easily... If you give gap

I feel the idea of leaving every alternate line does not give good look, rather give one little finger space after every word, it will give better look. Leaving one line blank, when you write in paragraphs, would be a good idea. On the other hand, if at all you want to leave one line blank, you can follow it, only if you write your answers pointwise or with bullets, in that case it would look good.
