It can be difficult to focus on your online course if you have a social media account open in another tab or are receiving notifications on your computer. When you’re doing classwork, avoid browsing the Internet, checking your email, and other distractions. If necessary, you can install an app that will restrict your access to certain websites during a designated period of time so you can focus on your studies. Never go into a study session undirected. Have specific goals each time you sit down to study. You can break the material up into chunks and study one chunk at a time. Make a schedule for yourself, with individual study sessions divided by topic. You should also remember your overall academic goals when you study. This can help with your motivation. Think about how a good grade will contribute to your overall GPA. Think about how the material will benefit you after the course. Simple memorization can only go so far. One of the most effective means to memorize material is giving yourself tests and quizzes. Quizzing can improve memorization because of a process called "retrieval." Every time a memory is retrieved, it becomes more accessible in the future. If there are practice tests and quizzes available online, take as many as you can. You can also make up tests and quizzes for yourself.  Flashcards can be a great way to test yourself on things like vocabulary and dates. You can also write down potential exam questions as you study. This can be very helpful if you're expecting an essay test. After you finish studying, take the test you made for yourself. Studying for long hours can easily lead to burnout. It's important to take breaks as you study. Take a break about every hour or so. Do something fun, like watch TV for a few minutes or go for a brief walk, and then return to your materials. You will find yourself feeling refreshed and recharged after a quick break. Remember, your instructor in an online course is a valuable resource. Just because you don't see them every day does not mean you can't reach out to them. If you stumble across anything confusing while studying, do not hesitate to send your instructor an email asking for clarification. If you have a web camera, try setting up a video chat meeting with your instructor for face-to-face feedback.

Summary:
Avoid online distractions. Have goals for each study session. Quiz and test yourself. Take breaks. Reach out to instructors with questions.
