GERTC follows a carefully designed review methodology that promotes gradual, consistent growth across all CELE subjects. Instead of separating lessons immediately into MSTC, HPGE, and PSAD, the review begins with the core engineering fundamentals common to all three areas. As students strengthen their foundation, the topics progressively become more advanced, specialized, and board-exam oriented. This structured progression helps students develop understanding more naturally while building confidence step by step throughout the review.
