First time poster but long time reader - thanks to everyone who makes this community work. I have tried to research before posting, so I apologize if this has already been answered. I have been using the Manhattan GMAT
video explanations and gmatquantum for quant expalanation, as well as manhattan gmat
for sentence correction explanations. However, I've been having trouble finding video explanations of the OG13 from a third party. Does one exist? I've learned a lot more from MGMAT and Magoosh
than I do from reading the answers in the back of the OG13 book, and was hoping there might be similar resources for CR and even RC. Thanks again.
