Understanding the DESCO Exam Pattern
Job recruitment exams in the power sector, especially those conducted by institutions like BUET and MIST, follow a specific pattern. The DESCO exam for EEE engineers typically consists of two main parts:
-
Departmental (Technical): This section carries the most weight and tests your core knowledge in electrical and electronic engineering.
-
Non-Departmental: This part assesses your aptitude in subjects like Bangla, English, General Knowledge, and basic mathematics.
Success in the DESCO exam requires a balanced preparation strategy that covers both of these areas.
