Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE tryout ( pid number, cname text, ppos text, decision text )
TABLE: CREATE TABLE player ( pid number, pname text, ycard text, hs number )
TABLE: CREATE TABLE college ( cname text, state text, enr number )

### Question ###
In which state is the college that Charles attends?

### Accurate SQL ###

SELECT T1.state FROM college AS T1 JOIN tryout AS T2 ON T1.cname = T2.cname JOIN player AS T3 ON T2.pid = T3.pid WHERE T3.pname = 'Charles'
