These online worksheets can contain open questions, multiple choice questions, discussions, links and more. You can design the worksheets based on the many templates offered by Wizer.me. The free version covers most features, but doesn't allow you to keep track of students' scores.
Privacy: Wizer.me doesn't require students (who are filling out the worksheet) to set up an account.
Easy to use: Wizer.me is a very structured and easy tool to use.
Quality: Wizer.me is a high-quality tool.
Options without paying: A lot of features are free. Only tracking students' performance and integration with Google Classroom is part of the paid plan.
