I am sorry to inform you that I am trying to solve the final exam of Ros basic path. I am actually facing difficulties. My simulation is loading continuously while other contents are working perfectly. So, I am now unable to check the simulation for my code. The final exam time is limited to 4 hours. I was hoping to get an certificate for this path. But now, It seems I am unable to get the certificate without trying to solve. I am hoping for some suggestions from the authority like what should I do? I have a problem like this:
Hi @marzanalam3,
I’m sorry about this problem but, first, let me assure you that you will be able to attempt this exam as many times as you want. Forget the 4 hours bit.
Now to the problem. I just checked here and found that the simulation is loading fine here, so there might be some problem on your side preventing it. Please try the following, in order:
- Try again. It might just work this time.
- Are you using a browser other than Chrome or Firefox? Switch to any of these two.
- Are you working in incognito or private mode? Please switch to normal mode.
- Try clearing your browser cache.
Please let me know if any and which of these works for you.
