Engineering courses can involve technical diagrams, calculations, design concepts, coding tasks, and problem-solving exercises that are not always easy to understand from online lectures alone. A topic may seem simple during a video lesson but become confusing when it is time to work through an actual problem. Some students may search for academic assistance or take my online engineering class support when they need extra help with their coursework. What has helped you understand difficult engineering topics online? Have simulations, worked examples, discussion forums, or one-on-one tutoring been useful? Share the methods or resources that have made technical subjects easier to study remotely.
