Asides the well known classical GRE video training which may cost a fee, there are also a few quality video materials on the youtube.
In the last few days, I have been privileged to browse through a number of GRE prep videos.
I present a glimpse of my findings below.
1. For the quantitative section, I would recommend "GREquantum" youtube videos which provides free video solutions to the Official Guide to the GRE Revised General Test. MagooshGRE also provides solutions to the Official guide to the revised GRE.
2. Also, for the quantitative section I recommend
GreenlighttestPrep videos for its organization, clarity, short length and summary at the end of each lecture. I also recommend
Magoosh GRE Prep Videos. They are both clear, informative and are a good guide for self study.
3.
Greenlight test prep youtube videos for the analytical writing section.
I think these videos are quite straight to the point. It gives very beneficial guidelines for tackling this section of the gre.
Greenlight test prep also has videos on youtube for the Reading comprehension
3. Khan Academy videos on quantitative section for those who want to get the basics.
I hope this helps.
Test Prep videos on YouTube are only a small sample of our complete course, which is entirely free.
