#1 go to http://www.gmatclub.com/
#2 click on FORUM (On the top row)
#3 You will get to the homepage of this forum.
#4 You would find a link 'Log In' on the top right hand side of this page...just click on it and when you put in your login id and password just check the box which says 'Log me on automatically each visit'.
Thats takes care of your password prob.
The firs thing you do on this site is to go to the LINKS section (again you can find that on top right hand side of of the page)
It would prompt you for login id and password...just give the same login and password which you had previously given.
Peruse this section...inside out...there are tons of useful resources in the links provided in this section.
Broswe through 'Verbal Questions'..try solving some queries posted by other members.
One good post is : http://www.gmatclub.com/phpbb/viewtopic.php?t=4253
same goes for Math...just browse this section...this section is particularly useful for Prob and Comb problems.
