before going to apply for that , make sure u know something about sciences. not only the physical sciences but the social sciences as well. be frank and just tell them what u have to say..

and make sure u apply from ur PC. dont use operamini or any proxy server.. that would make them reject u.

and know that the speed there might not be top notch all the time (even the site would load after a lag) as it is, fortunately, a community of serious yet common science lovers and not professional seedbox seeders and leechers
