Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Given, Alice & Bob have worked together for seven class periods in a row.
Calvin & Denny have worked together for three class periods in a row.
Calvin does not want to work with Alice.
Bob and Alice cannot work together since max 7 periods have completed.
So, the only possibility is Denny and Alice work together and, Bob and Calvin will work together.
