single select multiple choice question

Hi, I created a ms-form quiz with 30 questions and all these are single select multiple-choice questions. My idea is to give:
1 point if the answer is correct
0 points if no answer is given

-0,25 if answer is wrong
For all questions only one response is correct.
I would like to create a cloud power automate flow that does for each question the above calculation and after that update a variable that keeps in account the partial result. So in the end, I can have the overall score of the candidate.
Anyone has any hint on how to do it?

Hi @AlexPowerApps 

 

0,25 if answer is wrong ?

 

Is this 0.25 if answer is wrong?

 

Thanks



Did I answer your question? Mark my post as a solution!

Yes, that's correct. I found a way to calculate all this, but I think is not the best solution, since I have to repeat a conditional control for each question. So I guess there should be a better solution, even in the consideration that I need to update from time to time the questions and I should modify, by using this solution, all questions anytime. Too much time-consuming. I am thinking of another solution to better accomplish my tasks. 
In the meantime, anyone has an idea on how to loop inside each question for response ?
Thanks

Hi @AlexPowerApps 

 

Yes you can loop through all questions and then calculate the answer scores accordingly. 

 

Let me explain step by step approach. Also I hope you are trying the same via simmilar approach (may not be same)

 

I have used a sample like below:

 

Nived_Nambiar_0-1680429065657.png

 

Also, I have mapped questions to their correct answers in a excel file named Question_Ans.xlsx like below

Nived_Nambiar_1-1680429125314.png

 

MS Flow overall

MS Flow Step

 

Step 1: Trigger action: when form is submitted

 

Nived_Nambiar_2-1680429173851.png

 

Step 2: Get response details from form using get response details

Nived_Nambiar_3-1680429231881.png

 

 

Step 3:  Initialize a variable total_marks which stores the total mark for the quiz 

Nived_Nambiar_4-1680429264675.png

 

 

Step 4: List the rows present in Question_Ans.xlsx file which has correct answer details 

Nived_Nambiar_5-1680429310717.png

 

 

Step 5: To fetch all questions (names) of the form, i am using HTTP AD Connector which helps to retrive web resources from services authenicated from Azure Active Directory 

 

Nived_Nambiar_6-1680429540071.png

expression:  concat(triggerBody()?['resourceData']?['formId'])

 

In this connector, before entering the details like above, select the add new connection as shown below

Nived_Nambiar_9-1680429879274.png

 

 

and then enter the details like below

Nived_Nambiar_8-1680429807873.png

click sign in and select required account to autenicate.

 

 

Step 6: Use Parse Json to parse body obtained from above HTTP Request

Nived_Nambiar_10-1680430028567.png

 

The body would have question text, also question id (which is found in get response details output) which will be using to map things later.

 

Step 7. loop through each questions obtained from parse json action output using apply to each action.

 

Nived_Nambiar_11-1680430318491.png

 

 

Next steps will be action we did in the loop 

 

    Step 7a. Use filter array to filter the rows present in Question_Ans with the question id we are iterating through

Nived_Nambiar_12-1680430411842.png

 

 

Step 7b. use condition to check whether the question is present in excel or not like below

Nived_Nambiar_13-1680430467231.png

Nived_Nambiar_14-1680430508018.png

 

 

If question is present, go to branch: 

 

 Step 7c. Next bot will check whether the answer is null (not answered by user) 

 

Nived_Nambiar_15-1680430579850.png

 

 

using below expression in left side :  trim(body('Get_response_details')?[items('Apply_to_each')?['id']])

using expression in right side: ''

Nived_Nambiar_16-1680430710645.png

 

 

If above condition is true, we will go to yes branch 

 

Step 7d. Next use condition to check whether the answer entered by user and present in excel file is correct or not.

 

Nived_Nambiar_17-1680430929328.png

 

expression on left side of condition :  body('Get_response_details')?[items('Apply_to_each')?['id']]

expression on right side of condition:  outputs('List_rows_present_in_a_table')?['body/value']?[0]?['Answer']

 

If the above condition is true, bot will go yes branch and increment total_marks by 1 , if condition is false, it will decrease total_marks by 0.25. like below

 

Nived_Nambiar_18-1680431054722.png

 

 

Outside the apply to each loop, you can check the value of total_marks variable which denotes total mark for quiz

Nived_Nambiar_19-1680431108256.png

 

 

 

 

 

 

Hope this helps 🙂

Mark it as solution if it resolves your query 🙂

 

First of all, very thankful for your well-explained solution, I was developing something similar, but not equal. I created my excel file with two worksheets, one contains the solution for each question (the only correct answer), while the other contains some metadata columns such as id of the response, name, email, and all answers of the respondent plus another column where I can calculate the overall score. After that, I can use the "add a row on excel file" action to save the answers of the respondent plus other metadata and then I use the "get an excel row" so that I get the overall score finally I can, for example, send an e-mail to the respondent.
In any case, once I ended my solution, I let you know and after verifying that yours is working as well I will put a thumb up.
Thanks again.

@Nived_Nambiar , I let you know that I implemented another solution without the need to make use of a for loop. Therefore I haven't tried your solution, but considering your time and effort to suggest me I will mark it as a solution as well.

Hi @AlexPowerApps 

 

I would say you can explain your solution which u have tried without loop and then mark it as answer

 

 

Would like to know how u have done it without loop ☺️
