Well actually yes it is necessary to study everyday, I will give you a good reason and one bad reason.
1. (good reason) It is necessary to study everyday because you will never know what can pop up. It can depend on your life if you study. If you study more then you will know what to do during bad or good occasions.
1. (Bad reason) Even though is is necessary to study everyday it can also mess up your brain. If you keep studying then your brain will not have any time to rest or get some peace at the time. Putting to much on your mind at once can cause many things.
Here are both sides of the argument, thank you!
