GATE Exam: Preparation, Benefits, Syllabus, and Tips

1. What is GATE ? • The Graduate Aptitude Test in Engineering (GATE) is an all-India examination that primarily tests the comprehensive understanding of various undergraduate subjects in engineering and science. • The GATE exam is conducted on behalf of the National Coordination Board – GATE, Department of Higher Education, Ministry of Human Resources Development (MHRD), Government of India.

3. Why GATE ? • GATE preparation helps youappreciate,enjoyand improve knowledge of your B.E. course. • Increase chances of foreign placement. • Better quality job assured,especially if you prefer technical work. • Be called an IITianfor life. • M-Tech degree is must to teach in an engineering college. • In short better careerand higher salary.

4. Reasons for choosing GATE • Getting placed in PSUs(Public Sector Undertakings i.e., government-owned companies). • Getting M-tech. Degree from IITs & NITs. • GATE qualified students are also eligible for the award of Junior Research Fellowship in CSIR Laboratories and CSIR sponsored projects. • Just for Experience.

8. Difference betweenPercentageandPercentile • Percentage A percentage is a number or ratio expressed as a fraction of 100. • Percentile A percentile (or a centile) is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations fall. Percentile=((N-Your rank)/N)*100 N= no of peoples appeared in exam in individual stream.
