Hi I have just started to prepare for upsc this Feb of 2016 for the prelims is August 2016. Am I too late for preparing subjects like science.. The videos are good for people who cannot afford the expensive coaching classes and for people like me who have made the quick decision to write the exam after leaving their work. Thanks
