剑桥开放日学院不能进吗？

The Great Court may be viewed from under the Queens' Gate from 10.00 - 16.30 each day. Entry is via Trinity Lane. Public Entry into Great court and The chapel during the same hours is via the Great Gate in Trinity Street. There is a small fee to enter the College, for Adult tourist visitors the fee is £2 and for Children visitors £1. The Wren Library is generally open to the general public between 12 noon and 2.00 pm Monday to Friday and on Saturday mornings in Full Term from 10.30 am to 12.30 pm. Access to the Wren Library is free. If you want to visit the Wren only you should enter from Queen's Road or Garret Hostel Lane. It is not possible for the public to enter other parts of the College by this route. The tourist porter at the Great Gate is happy to let visitors know which parts of the College are open.

Open day is for prospective students/families to know more about the college before applying.
You can enter if you say you have that purpose. But I think perhaps they may require an advanced registration.
