React.js videos unaccessible

The react.js videos are displayed but are unaccessible. It says the videos will be updated on the 31st of May. The exam guidelines say that all videos should be watched, but I have only completed 74% of the course.

I would like to know if I should wait untill react.js is available or should I proceed with my exam.

@AtaAbbasMirza as mentioned in the training content, you can go ahead and answer the test as the React content will be only present in the test once that content is live.
