A simple answer will address your question: the admittance rate at MIT in 2018 was 7.2 percent, which is extremely difficult. MIT's GRE average scores are as follows:

Verbal: 155-163 on the GRE

Quantitative GRE: 155-167

4.5-5.0 on the GRE AWA

A higher quant score is required for engineering or math-related programs.

A better verbal score is required for an anthropology or verbal related program.

Hope this helps
