Hands-on 9 quiz answers marked incorrect

I greatly appreciate your help.
I was able to match the results and continue the training.
I have completed all 15 modules, and most of my quiz scores are 80-100.
I got a few quizzes with a score of 66.67 (or 6.67).
The overall grade of all quizzes should be above the 70% pass mark.
However, I could not view the certificate, and the progress bar is at 98%.
Do you have any idea about this?

Thank you

Great news @shetob. I don’t manage the Open University platform, so I would recommend contacting their support team directly for assistance.

I’m also not getting correct answers although I started fresh using version 5.6 and checked that I have done all the steps. My emission peaked in 2025 while in the example shown on the hands-on instructions, the emission peaked in 2029. Please find here my model back up and and the txt data. Kindly help.

Dear @erin, your data file is correct, and the emissions peak in 2025. The graphs in the hands-on guidelines are outdated, but your model is correct and the results match the reference case.

Could you please let me know which quiz questions are being marked as incorrect and what values you are entering for your answers?

Thank you for your response. For question 1, I answered 3122.12 (as in the image attached), and for question 3, I put in 16.11.

Dear @erin, regarding Question 1, the issue is probably due to rounding, so using 3122 should work. As for Question 3, the results are quite unusual, as they are much higher than those in the reference case. I still have the model you shared previously, and the results you obtained do not match the ones you reported. Please see the image below for comparison.
