Recording is not in Sync Error Handling Concept

Hi Team,

I have been facing below 2 issues.

- Currently, I am on video-3 but there are lot of issues with the buffereing...Trainer is talking something different and video is presenting something else. For Ex-during presentation of "Raise" Method trainer is writing the code of raise method and scree which is visible is about the help menu for raise method and this is not the only instance, it;s just an example. Material and way of training is worth appreciating but due to this syncking issue, sometimes does understand the whole concept which is key goal.

-For error handling concept, couldn't understand becase error is in the 3rd line of code and you have written &Err.number in the 2nd line. Could not understand the concept of error handling. KIndly help to assist with understanding this concept as it's going to play a crucial role during live projects.

Thanks in advance for your support!
