College rankings by selectivity (Questions)

Colleges and Universities A-Z Rensselaer Polytechnic Institute

I was given this list made by the NY Times a few days ago. The person that gave it to me claims it has been updated every year since 2013, but I have no idea how to verify this. Is this ranking still relevant?

Here ya go.

I made this a year ago from the IPEDs database.

Basically I ranked the schools by:
1 acceptance rate
2 SAT scores

Then I averaged those 2 rankings (a+b)/2 and ranked the avg ranking value to figure out the hardest schools to get into.
