Why last minute reading is unhelpful

While in my high school, I had a classmate called Jennifer who was famously known for last minute reading and spotting what would be set in the exam. Jenniffer was always engrossed in mills and boons (romance novels) during class and prep time. Her obsession was too much that all she would even cram and repeat what she has read in the novels clearly like she was the author.
