<p>I am not sure if this is appropriate but oh well...
My greatest liability is CR and I have heard that Grammatix is perfect for that. I checked their website but the price for the hard copy is ~70$, a little too much for my pocket as I usually pay for all of my test prep stuffs.
Just wondering of anyone have a spare copy of grammatix I can buy for under 30$</p>
<p>Check Craigslist</p>
<p>Its probably available online (PM me for more details)</p>
