The first step towards your preparation for any competitive examination is to understand the pre-requisites for the examination. You must thoroughly scan through the syllabus of the exam (you get that easily on the Internet). Besides the syllabus, you must make a note of the weightage of various subjects, so that you can plan your preparation accordingly. Scanning through a few previous years' questions papers helps to get an idea about the exam pattern.

Once you understand 'What to prepare?'  it's your turn to plan 'How to prepare?' Make a time-table with both short-term and long-term goals that would help you in timely preparation for the exam. A time table makes you more disciplined and helps you to get rid of haphazardness.

Focus on understanding the concepts throughout your preparation. Do not adopt rote learning technique. Understanding helps you to remember the concepts for a very long period of time. Moreover, with a clear understanding of the concepts, you can comfortably handle questions related to those concepts.

You can also create your memory tips or interesting acronyms to remember formulae or equations or difficult terminologies.  You should always make your own short notes in your own way, as they help you big time to revise a few days before the exam.

Studying alone doesn't make your preparation complete. You must evaluate yourself time-to-time for an effective preparation. You must write sample papers for the competitive exam you are preparing for.

'Belief' is a very powerful tool. You must believe in yourself and your preparation. Ensure that you study the same way throughout the year, to avoid last minute rush and stress. Spend 10-15 minutes before going off to sleep to quickly recap all that you learnt throughout the day.
