During my preparation for Toefl, I found TST Prep
and their videos to be the most useful amongst the ton of videos available on this topic. Josh is always to the point and provides invaluable advice that is easy to follow. With only 2-3 days of prep (during which all I had time to do was to view their practice test and tips), I was able to achieve my targets. I also believe with a little more effort I could have done even better. TST prep was so crucial that I am sure that without these videos, I would not have achieved my targets.
