OLExpert’s pricing is dependent on the plan you choose. Plans vary as per grade and the exam a student is preparing for. Also, students can customize the topics as per the requirement. The quality of OLExpert’s content is really great and made it in a very interactive manner.
Video Lectures: OLExpert’s online lecture is an educational lecture designed to be posted online. Lectures are recorded to video, audio, or both, then uploaded and made viewable on a designated site. Videos lectures increase student engagement, which in turn helps boost achievement. If students are interested in the material, they will process and remember it better.
PDF Notes: Creating short notes, highlighting pertinent points, and making these as easy to access, organize and reference as possible should become a priority. This will ultimately help with information retention, as the concentration and active listening it requires will fire up cognitive processes that enhance learning.
Practice Questions: Questions have long been used as a teaching tool by teachers and preceptors to assess students' knowledge, promote comprehension, and stimulate critical thinking. Well-crafted questions lead to new insights, generate discussion, and promote the comprehensive exploration of the subject matter.
