Web based assessment tests in Maths and Science for CBSE & ICSE students

I was in search of web based assessment tools for school students. I found one site 24x7Guru.com, which is providing 100% web-based assessment test packs for classes 3 to 10 of CBSE & ICSE students in Science and Mathematics subjects. Test papers constitute of chapter-wise and periodic tests in Math and Science.

Thats cool I visited 24x7guru.com, it seems they are conducting Destination Nasa contest, winners will have the golden chance to visit NASA. Hope this contest will be conducted next year also as my son is not eligible for the contest he is in 5th std now.
