My progress doesn't get updated!


Hi. I am doing on Python, but my progress doesn't get updated. I have done to 30% in school library desktop but when I logged in by my own pc, it shows me only 12%, which was done by my own pc 5 days ago.
So it means, I did it by 12% using my pc, and then by 30% using other pc. And now I logged in by my pc but progress shows me 12%, not 30%. I delete my cache but it doesn't work. Help me...
