Data Entry best practices

I have several data entry boxes that the user will need to input X values and be able to know if the values enter are the correct ones.

Question 1: What is the best way to do this setup?

Question 2: Can all the data entry boxes linked so the results can be sent to an LMS? i.e. You entered 2 of 3 correct or 3 of 3 correct etc....

Anyone can share any examples like this?

P.S The answer enter in the Data entry boxes will be a combination of Numbers, letters and Symbols. Something like this (3,4x)....
