Hello.
Cracking JEE advanced exam by just one year self study preparation is not a big deal if your preparation strategy is productive, some tips I can give you, by going with these hopefully you would be able to have good outputs:

• First analyse entire syllabus of JEE advanced and also analyse previous year papers to find out high weightage topics,
• Try to clear doubts on your important high weightage topics
• Consistency is important .
• Try to refresh your mind along with your study .
• Always do smart study, i.e, exam oriented study.
• Don't pile up doubts.
  

Best of luck.

First know the entire syllabus. Then make a proper and programmatic study schedule which you'll follow throughout your preparation. Instead of choosing a random topic from the syllabus, you must break your preparation into sections. Sub-topics from each section should be selected and then strategy on clearing concepts must be made. Make your own notes. Never leave any concepts doubtful or unsolved. Once done with the syllabus and concept clarity, you should move towards solving previous years papers. Give mock tests as much as possible. Time management is one more important thing you should look upon. Remember that practise will increase your efficiency. Get the best books for preparation. NCERT Textbooks of class 11 and 12 are best for basic preparation and concept clarification. Once done with this, you can move on to other books. Try to give one mock test in every week so that you can understand where you're standing.
