Another factor that will affect your choice is your level and style of learning. Depending on your prior knowledge and experience, you may want to look for platforms that offer courses that match your level of difficulty and challenge. For example, if you are a beginner, you may want to look for platforms that offer courses that are easy to follow, interactive, and engaging, such as Khan Academy, Duolingo, or TED-Ed. If you are an intermediate or advanced learner, you may want to look for platforms that offer courses that are more in-depth, rigorous, and analytical, such as Harvard Online, MIT OpenCourseWare, or edX. You should also consider your style of learning, and look for platforms that offer courses that suit your preferences. For example, if you are a visual learner, you may want to look for platforms that offer courses that are rich in graphics, videos, and animations, such as Skillshare, CreativeLive, or Udemy. If you are an auditory learner, you may want to look for platforms that offer courses that are based on podcasts, lectures, and interviews, such as Coursera, Audible, or MasterClass.
