Is the Asvab as easy as people say?

I took the Picat and scored a 48, I was then given a few weeks to study for the Asvab. I was just wondering how easy/hard it is and if I needed to know any information or if anyone has any advice before I go take the test. I recently bought the book and it’s been helping a lot. I was only watching grammar hero and taking online practice tests which got me the score of 48 on the Picat. I wanted better jobs and more opportunities so I bought the book to get a better score.

Some people say it’s easy and most people didn’t study for it at all, I personally have been out of school for a while and needed a refresher.

Which subjects should I mainly focus on in the book? Also does the mechanical and electrical sections have a lot of impact on my overall score?

Any advice or information would give me great clarity. I just need a bit of reassurance so I’m not stressing too much.
