@youcee, you don’t have to guess! 
In terms of stats and the admit rate, the site I mentioned earlier, the American Society of Engineering Education (http://profiles.asee.org/), gives the admission numbers and stats just for engineering (but it does not break down admissions by gender).
Example: The University of Texas at Austin - 2015
Engineering:
13,362 students applied
3,376 of those were admitted (25.3% admit rate)
Mid 50% SAT for enrolled freshman
1920-2180
Mid 50% ACT for enrolled freshman
30-34
Percentage of entering students ranked in the top quarter (25%) of their high schools: 99%
Common Data Set for entire university:
43,592 students applied
17,006 of those were admitted (39% admit rate)
Mid 50% SAT for enrolled freshman
1730-2070
Mid 50% ACT for enrolled freshman
26-31
Percentage of entering students ranked in the top quarter (25%) of their high schools: 91.7%
I just randomly picked a large state school that had been mentioned by a different poster as more selective for engineering than the general population. Now I’m curious about my daughter’s choice.
Example: Northeastern University - 2015
Engineering:
7,566 students applied
2,916 of those were admitted (38.5% admit rate)
Mid 50% SAT for enrolled freshman
2088-2240
Mid 50% ACT for enrolled freshman
31-34
Percentage of entering students ranked in the top quarter (25%) of their high schools: 97%
Common Data Set for entire university:
50,523 students applied
14,388 of those were admitted (28.5% admit rate)
Mid 50% SAT for enrolled freshman
1980-2240
Mid 50% ACT for enrolled freshman
31-34
Percentage of entering students ranked in the top quarter (25%) of their high schools: 93.9%
Knock me over with a feather. The student profiles are virtually the same but the admit rate is higher for engineering.
