Serious bug found in answering question

I was attempting a question which was unrated and it had no solution, While I entered the first answer it came out to be incorrect, Then by mistake I clicked on 'no soultion' button the page where solution are shown was taken to, Though it did not had any solution still the correct answer was shown on the top, On the left hand side I clicked the back button and then as I still had attempts left I entered the answer and It said "CORRECT".

I found this strange and searched for another question which did not have any solution and repeated the process, I am adding the steps as I did

I entered a random answer, (Note that the problem has no solution yet it the question does not let me click on the No solution button,) and it came incorrect

2 When I entered one wrong answer it let me click on the No solution button

3 See that the correct option is written on the top.

I came back and entered the correct answer

5 And it says "CORRECT ANSWER"

This is what I found strange, This bug works for problem which has no solution yet, I will request someone to look into it.

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.

Sorry @Charlton Teo, One of the question had to be sacrificed, I didn't intentionally choose yours, It was the first unrated one that appeared to me. Sorry

nah I dont really mind XD but on topic: This would be easy to farm points

@Calvin Lin , @Peter Taylor ,@Silas Hundt ,@Pi Han Goh ,@David Mattingly ,@Finn Hulse ,@Mursalin Habib ,@Sharky Kesa ,@Daniel Liu

Not good. People can cheat from this. Does this only happen to unrated or is it for all problems?

Sharky Kesa - 6 years, 11 months ago

This is a very serious bug, definitely.

@Sharky Kesa – Yes, It would be much problem if someone level 1 and 2 would do this with a level 4 or 5 question, The questions rating will drop drastically, and the user's will increase drastically

@Ishan Tarunesh – Yes. Delete this discussion so no one will know. Email the Brilliant staff instead.

I think it is for all question(even the rated ones) which do not have a solution, But I tried on unrated ones because I did not want to loose rating by guessing first answer.

@Ishan Tarunesh – I have also noticed that bug

Ronak Agarwal - 6 years, 11 months ago

@Ishan Tarunesh – I don't have much o lose. My NT rating is over 2400 so even if I get a question wrong, it won't go down a level.

@Sharky Kesa – Yeah same. :P

Finn Hulse - 6 years, 11 months ago

Thank you for reporting this bug. We will fix it.

Calvin Lin Staff - 6 years, 11 months ago

Hey everyone, I believe this is related to some changes we pushed yesterday. We'll look into it today.
