Update data

[wongjingping]

We make the following data changes:

• Add students graduating in < 10 and > 10 years for advising. This is to allow our data to test if the SQL contains a filter for the past 10 years for the following question: How many students were predicted to graduate in the last 10 years?. Currently all of the available data is within the "past 10 years" hence it won't test if the SQL actually filtered correctly for the past 10 years.
• Add reviews < 10 and > 10 months to allow our data to test if SQL accurately filters past 10 months since today.
