The first thing you need to remember is that to prepare well for GRE, IELTS/TOEFL. You do not need to panic. To develop a careful understanding of your planning, you need to first determine where you need to concentrate first. Set aside at the beginning just 15 minutes a day for your training.

Start writing down one or two life experiences in minute details every single day.
