Are you an intensive or extensive reader?

I consider myself more of an intensive reader. When doing English, or preparing for my examination, I often cannot dive deep into it and fully understand the materials. So I find myself more focused and able to memorize things in a small, systematic way. That approach allows me to gain in-depth knowledge of the content.

Actually, I'm not a big reader. I only read books related to my profession. I read books that help me improve my skills and knowledge. I think I'm an intensive reader because I focus on the main points rather than reading the entire book. This saves me time.
