General GMAT Questions and Strategies | Re: Urgent help required

Sir all the questions asked by you i have answered them in my other post where you have replied. I am ready to do what ever hard work it takes. Please suggest free portals as i can't afford to spend 250$ or 500$ right now. I can buy few test series. Few of my college seniors have got 720,680 just by online free stuffs i don't know how.. But i couldn't ask them the source at that time and now they are out of connection.
Thanks
