Tips to Use Online Courses Effectively 

Online exam prep courses are the answer to a busy life. The convenience of studying at your own time and place can’t be overstated. Once you purchase your course, start any time. Here are study tips to help you succeed:
  • Prepare a quiet study space – most people study their best in a quiet environment, but that doesn’t mean you can’t play some tunes if that helps you get in the groove
  • Set up a realistic schedule – with two exams you don’t want to rush yourself.
  • Self-Care: eat, sleep, and exercise – if you’re exhausted, stressed, and not eating well, your brain will not function optimally
  • Take breaks. Take your prep seriously, but be sure that you have time for other things you enjoy.
