Detailed ISRO Mechanical Syllabus for Scientist and Engineers Exam
Last Updated: Dec 30, 2025
Interested candidates who applied for the ISRO Scientist/Engineer ‘SC’ examination in 2018 can access the detailed syllabus right here on this page to kickstart their preparation effectively. Those eyeing prestigious central government jobs with ISRO should dive into studies without delay, as the authority has not issued any standalone syllabus notification separately.
The written test follows the standard BE/B.Tech curriculum in the relevant discipline—such as Mechanical, Civil, Electronics, or Computer Science—and consists entirely of objective-type multiple-choice questions testing core concepts, numerical problems, and practical applications from undergraduate engineering courses. This approach ensures candidates demonstrate strong foundational knowledge aligned with ISRO’s technical requirements for scientist roles. Begin your focused preparation today to excel in this competitive recruitment process.
