GATE EE 2025 Exam: The Graduate Aptitude Test in Engineering (GATE) 2025 has provided the candidates with a structured framework to prepare for Electrical Engineering (EE) with subject-wise weightage. Electrical Engineering core subjects together contribute for 72% of the total marks making it a core subject of this exam. General Aptitude contributes 15% and Engineering Mathematics contributes 13%, so it is very important for the aspirant to get hold of these areas as well as the core topics. GATE EE 2025 exam will be conducted on February 2, 2025 from 2:30 PM to 5:30 PM.

Important subjects with significant weightage include Electrical Machines which carries 12 marks, followed by Power Electronics at 11 marks and Power Systems is 8 marks. Besides other important subjects like Signals and Systems and Control Systems, each carries 8 marks. For better preparation, candidates should prepare high weighted topics based on these subjects like circuit analysis techniques in Electrical Circuits, stability analysis in Control Systems, and principles of operation in Electrical Machines.
