HI Maria 00009,
Welcome to the Gmat club.
here u can find the link for the review of gmat pill http://gmatclub.com/forum/gmat-pill-study-method-recommended-93417.html?hilit=GMAT%20Pill
as far as my reviews for this prep i will say there SC part is good but its more a concept based study method..they have tried to teach common concepts which u may have learnt already if u have done a lil bit study for GMAT.
In my personal opinion i will not recommend u this method for the whole course..u can try for individual parts like SC..
it will cost u arnd 327$ after discount which is not worth the value..u wont get RC part with it.There PS concepts is also not that much good..They have solved some questions with normal method which u can easily solve with shortcuts learnt from other guides..I will say its better to buy manhhattan GMAT guides then going for this method...
*the above is my opinion...
