I really doubt about CSEVideo.
CSEVideo is very popular among students. I also subscribed it for several months and very disappointed of it and regret it.
1. POOOOOOOOR video/audio quality:
The volume is too low even on maximum volume. They recorded it without an individual microphone.
2. Too difficult to use on multiple devices:
They are too worried about sharing the service among students or doctors. So even the legal users cannot use them with two different devices if I forgot to log out from the original device. And for me, even though I logged out, I still cannot log on to another device. Furthermore, don't expect any help from them. They NEVER give you a reply except for things about purchasing or price before you buy it.
3. Too fast, not relevant questions:
I admit it follows FA well. But to ask all the questions on the table and do all the P/Es in the book, the doctor in there do them in a SUPER high speed.
4. Wrong P/Es:
Search for verified references and compare them with this.
If you're worried about the CS exam, I recommend CSEVideo just for 1 week just to taste how the exam goes. I'd rather give one point to UWorld CS.
