select * from STUDENT s inner join ADDRESS a using(POSTAL_CODE) where a.PLACE_NAME like '%Toronto%' and s.PROGRAM_NUMBER = 'BSC2'

instead of select * it is better practice to suggest fields like
FirstName, LastName to maintaine data integrity in the future (mainly
used in the industry when databases are constantly changing)
