Take some time to think about what your greatest challenge is. That is the "frog" that you need to tackle first. Make a plan to tackle that first. This principle applies to ACT prep as well as everything else in life. Make a note in your course journal about what you will be tackling first. You may want to find an accountability buddy to help you stay on track with it. Regardless of when you do your ACT prep work, make sure it is one of your priorities. You can do this!
