Bridgewater-Raynham Regional High School has planned an event called “After the Acceptance Night’’ at 6:30 p.m. March 27 to supply families with information on ways to pay college costs. The program is offered by the Massachusetts Educational Financing Authority, known as MEFA, a nonprofit organization that helps families plan and pay for college. An experienced representative will provide an overview on college billing cycles and options for payment. The program will also offer guidance on interpreting financial award letters. All college-bound seniors and their families are invited to attend the free event.
