Focus and determination matter a lot in GATE exam preparation, and that only comes when you decide to go for it.
Once you are thorough with the exam pattern and syllabus, list the topics to study according to their difficulty levels.
The GATE exam has 65 questions you need to answer in 3 hours. It means you have a little over two minutes to answer each question.
There is no substitute for constant revision. Prepare a revision schedule and ensure you revise all the topics thoroughly every week.
Test yourself repeatedly by solving sample papers. Be thorough with the previous year's papers and their solutions.
Ensure you practice using them on your laptop or computer screen to avoid the hassle of the day of the exam.
Keep peer pressure at bay, and do not stress. Do not neglect your food and sleep timings. Stay healthy.
