VidyaCenter.com, a new educational website launched by Suyash Katyayani (ex. IIT'ian) can help you prepare for your IIT-JEE exams, your CAT Exam, get advice on Job/Career or ask about what books you can read to prepare for the interview etc.
You can join the website as a student or teacher. If you have joined as a student, you can ask questions on topics such as Maths, Physics, Chemistry etc. You can also take free JEE or CAT mock tests for your preparation. I saw students posted questions to the site to get answers. This can be misused by students as they can get ready answers without studying or learning.
If you are join as a teacher, you can answer questions asked by students or can sell your services, materials to students. I was surprised though that anyone can join to VidyaCenter as a teacher. Who would verify the qualification of the teacher? Who can verify the answers given by the teacher?
The site also has content shelf section where you can find materials for job interviews, exam questions, video tutorials and pdf files on many subjects.
This can be a good free online resource for some JEE or CAT study materials though. Check out VidyaCenter.com
