Thank you, Writeacher. I corrected my sentences. Do they look correct now?

What is the English words for the books which has many test problems which were used for taking tests?

Answer 3

In sentence 3, it should be "shine" not "shined."

Those books could be test-prep books, textbooks, or reference books, as you said.

Answer 4

I would suggest that you use - Leaning back against the sofa, I watch the TV.

This indicates that it is you leaning against the sofa, not the TV.
