I was given the wrong answer the last time I asked this question. Please give me the right answer this time.

A couple is planning to finance its three-year-old son's university education. Money can be deposited at 7% compounded quarterly. What quarterly deposit must be made from the son's 3rd birthday to his 18th birthday to provide $3000 on each birthday from the 18 th to the 21st? (Note that the first deposit is made three months after the 3rd birthday and the last deposit is made on the date of the first withdrawal.) (keep 2 decimal places)
