Open Study is an educational site which allows students around the world to help each other in studying on various topics from Biology to English.
How to Start:
Setup is very simple and an email address is the only necessary tool. Once you create a username and password and insert an email address you are taken to a page where you can select a subject such as the picture below. Overall there are more than 20 subjects in which to ask a question. Once you have clicked a subject you are brought to a page where questions can be asked or answered and the person who gets the highest answer vote receives special points.
How it helps:
Open Study has a simple design in which students can ask question whether it be for homework, clarification or studying. In addition to ensure safety and respect there are moderators who monitor all the questions and their responses and in special cases remove people and their responses.
