Table of specifications
Subjects and weights
The MELE is scored across 3 subjects. Each one counts toward your general average, so the reviewer gives every subject the depth its weight demands.
| Subject | Weight |
|---|---|
| Industrial and Power Plant Engineering | 35% |
| Mathematics, Engineering Economics and Basic Engineering Sciences | 35% |
| Machine Design, Materials and Shop Practice | 30% |
| Total | 100% |

How the MELE is passed
A general average of at least 70%, with no subject rating below 50%. You need a general weighted average of at least 70% with no subject grade below 50% (RA 8495). Engineering boards pass at 70%, lower than the 75% of most PRC boards.
