Check out some of the helpful strategies given our experts and GATE toppers listed below: 

• Start with Engineering Mathematics + GA: This section can easily give 28 marks combined. Begin with GATE preparation based on the topic weightage accordingly. 
• Target the high-weightage core subjects first: For CSE, the high weightage topics include OS, Networks, DSA, DRMS, TOC. For ME, it consists of Thermodynamics, Manufacturing, Machine Design. Moreover, for CE, students can focus on Structural Analysis, Fluid Mechanics, Geotech Environmental as priority topics. 
• Practice NAT questions regularly: NAT questions have no negative marking so accuracy can give you more advantage. 
• Attempt at 8-10 full-length mocks in the last 60 days. 
• Aspirants who are willing to get into PSU and MTech courses can target combination papers such as EE+IN, EC+IN, ME+PI or CS+DA to increase their chances. 

The GATE exam subject list is more than a checklist, it is your strategy map to a top IIT, IISc, NIT, MTech seat or a PSU job offer. The syllabus has been revised for the first time in five years, therefore aspirants must prefer from early on to master the newly added topics. Make your preparation easy with the MADE EASY GATE 2027 courses and crack your GATE dream.
