Level problem

I didn't do any geometry problems today but my level went down to 2. I checked my activity for the day and it says my geometry got leveled up. What's up with that?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Weird. We'll look into it today.

I have the same problem with my Combinatorics level just now. I noticed it went down one level eventhough I didn't do any problems on that level.

Hi Venture,

I see that you had worked on geometry problems before you made this post. In particular, for the time period that is 1 hour before and 3 hours after you made this post, you gave answers in geometry 12 times (might be to the same problem), of which only 1 was correct.

The problem which you got wrong and caused the downgrade, was Follow The Fold, where you gave the incorrect answers of 21, 27, 35.

You leveled up 'yesterday' (but still within a 24 hour period) by solving The Circumcircle And Tangents. As you were barely over the threshold, subsequent wrong attempts pushed you back down.

If this does not reflect your activity, I would encourage you to keep your account secure. You should change your password, and log out from computers that are publicly used.

Calvin, now my combinatorics level came down to 2. Why? I didn't do any combinatorics problems at all.

Hi Venture,

I looked into your history again, and what I found echoes my original comment.

In the 2 hours before you posted the above reply, I see that you worked on 2 combinatorics problems. They are Grocer's Last Problem and Random Answer Correct. You got both of them wrong. When you got the first problem wrong, your rating dropped below 1500 and hence you moved to level 2. I see that you subsequently answered the second problem and got it correct, which raised your rating back above 1500 and hence moved to level 3.

I noticed that in your recent reply to Silas, you made the comment "even though I didn't do any problems on that level." Please be aware that problems which are not in your level will still affect your rating. (We have a cutoff for problems that are substantially below your level)

For me to troubleshoot further, I would need more information.
1) Do you recall attempting the Geometry problem Follow The Fold?
2) Do you recall attempting the Combinatorics problem Grocer's Last Problem?
3) Do you recall making the first attempt on the Combinatorics problem Random Answer Correct?
4a) If yes, are you unaware that they were problems in the respective topics that would affect your rating?
4b) If no, is there the possibility that someone else has access to your account?
5)

@Calvin Lin – Yes I did made an attempt on Grocer's Last Problem but I still have 2 more tries. So I guess we get penalized eventhough the first and second attempts are incorrect whilst the third might be correct?

Venture HI - 7 years, 2 months ago

@Venture Hi – Yes, your rating drops immediately if you submit a wrong answer. It will drop further as you submit more wrong answers.
