ISRO recruits students for the posts of SC. The exam is conducted for various streams like CSE, ECE, and ME. The exam has two phases Written and Interview. ISRO Exam Preparation Strategy for ECE branch:
1- Cover the syllabus thoroughly: The syllabus for the Indian Space Research Organisation exam is not publicly stated, but we have tried including the syllabus based on the weightage review of previous papers, which will aid students in their preparation for the ISRO exam. Smart work is key in this process as the students are expected to build conceptual clarity as well as a strong foundation on all topics and that too in a particular time frame.
2- Study Plan:
The next most imp thing that students need to do is list out all the imp topics according to their marks weightage in the previous year's question papers. This will help them immensely in the preparation process.
3- Test Series:
Test series are the most imp part of any competitive examination. Students should attend mock tests to evaluate their preparations before finally sitting for the examination. This will help you to improve your weak area and give you confidence for exams.
4- Other Imp Tips:
Students should skip irrelevant subjects and focus on the essentials. This would save you time and effort. Graduate Aptitude Tests in Engineering and Indian Space Research Organisation exams are very similar in terms of questions asked, difficulty level, syllabus, etc. So, students who are preparing for GATE have an upper hand in the ISRO examination. Syllabus: Electromagnetics, Communications Systems, Electronic Devices, Networks, Analog Circuits, Digital circuits & Microprocessors, Control Systems, Signals and Systems, Microwave Engineering
Resources:
Questions asked in the Indian Space Research Organisation examination are completely similar to that of the Graduate Aptitude Test in Engineering syllabus. Candidates need to prepare for the Indian Space Research Organisation examination based on the Graduate Aptitude Test in Engineering syllabus and undergraduate curriculum. ISRO examines the previous year's questions. Previous year's questions of Graduate Aptitude Test in Engineering, Defence Research and Development Organisation, etc. Indian Space Research Organisation questions are based on facts, formulas, methods, and techniques.
