    【Question】
    Among the universities with over 20000 students in 2011, how many of them have an international students percentage of over 25% in the same year? in 2011 refers to year 2011; with over 20000 students refers to num_students > 20000; international students percentage of over 25% refers to pct_international_students > 25;

    【Evidence】
    in 2011 refers to year 2011; with over 20000 students refers to num_students > 20000; international students percentage of over 25% refers to pct_international_students > 25;

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT COUNT(*) FROM university_year WHERE year = 2011 AND pct_international_students > 25 AND num_students > 20000
