You of course know of the popular saying “there is no place like home”, which came from some super old movie that was made like 100 years ago. I can’t remember exactly which one, but that is totally not relevant anyway, although the saying itself is. When it comes to studying for a big exam like the CISA one, you will need lots of quiet time, and I feel that apart from perhaps the library, the number one place you can find this quiet time will be in your home. Your bedroom would be best since only few people will ever need to go in there during the day when you would, I suppose, be doing your studying, or be wanting to do your studying, I should say. You could maybe also use a study room if your house has one, or really any room where there is a chair and table for you to sit at, where people won’t be able to make noise around you.
Along with quiet studying time, the other key part of great study for this exam is having the best CISA study guides. Use those in your spare time and the exam will not cause you too many difficulties.
