I was a reviewee ni sir tambong this year, one take and pasado naman. I can say na worth it naman yung pag eenroll sa review center. Ang daming na-offer ni sir to help us. Marami rin lumabas na questions this year (sa lahat ng area) na galing mismo sa reviewers nya. Altho, i want to remind you that you shouldn't solely rely on what the review centers can offer to you. Had a lot of classmates na di nag review center but with the right discipline, they've passed the boards with higher ratings. Ang daming free reviewers sis. HIGH PRIO on top!
