Get a great Study Guide for yourself:

PHR certification books come costly and if you really want to make the best of the study material you buy, make sure you buy something that suits your learning methods and helps to do better. Find something with online study support and work hard to make yourself learn everything you need to. Studying for PHR is definitely hard work and you need to figure out time and dedication for what you are pursuing. Attempt more and more practice tests:

This is extremely crucial if you want to get a real hang of the concepts you are going to be tested upon. There are a large number of resources available online for free or at a reasonable rate. Buy a book of practice exams and take them on regular intervals to spot out your weaknesses and sort them out over time as you prepare yourself for the test.

Keep a track of time you spend on your prep:

Make sure you have enough time at hand to cover all your study material and revise it at least once before taking a chance with your certification examination. Make a routine for yourself and stick to it to make the best of the prep time you have at hand.

Recreation is crucial:

Be it a hobby or some random activity you enjoy, make sure you find time out to enjoy it. Studying for your PHR can get quite monotonous and hectic and you cannot afford wasting your precious hours pretending to study something you are hardly enjoying. Instead, take a break, plug in your headphones and go out on a long jog to refresh your senses every once in a while.

Get help if you have a family to deal with:

Study prep can be straining both mentally and physically testing, and if you have a family to handle or kids to take care of, it becomes a lot more difficult. Try having help over to handle the kids or get someone to do the chores for you. Learning to multitask can be of great help too.
