Hi, recently I was demoted from Level4 in Physics to Level 3.Fair enough, I did only one question last week. But I solved all the questions this week on level 3, which got me thinking. I am not able to do level four, but I can do level three quite easily. And in the future I may again be promoted to 4.But I want to stick to level three. Same goes for other two categories I am fine with level four of geometry and combinatorics, though I solved all the questions this week.Can I LOCK my level? That is, can I have an option if I want to increase my level or not?
