The topic-wise GRE videos were extremely engaging. The videos are not very long, and I found them very useful. The best part I liked about Oak's GRE prep was that after watching a video, I could immediately attempt practice questions for the specific topic. The questions had detailed explanations and were very helpful. I am glad I bought Oak's Self-Prep and would recommend it to anyone looking for bundled online GRE prep at an affordable price.
