Physics for JEE/NEET : Timeless Thumb Rules

How can I improve my conceptual understanding of Physics?

Reading only one textbook for at least 2–3 times and solving all the numerical problems of that book. Also, modify those 
numerical problems, play with them! ….Then start with thought experiments. Also, engage with your teachers & parents.
How do I plan my 'study' to cover all the chapters for the JEE Physics without stress?

Step 1: 

Read HC Verma; solve all the questions. Don't worry if you can't solve all the questions. Just keep a track of those questions. Don't ask any doubts till the next 3 months. STOP using the INTERNET for the next 3 months. Get hold of a good mathematics book (ask your Mathematics teacher) and complete the first few chapters on Coordinate Geometry; Differential Calculus.
Step 2:
Armed with a lot of confusion & doubts, consult any teacher. If you need help after 3 months, message me. I'll help you! This is just my contribution for the universe.
Step 3:
By now, you must've understood a lot about JEE. Prepare your own strategy. OR read the success stories of top 100 rankers and get inspired to make a hybrid strategy.

As we know, the exam consists of multiple concepts. What would be the best preparation strategy for solving these questions?
Take it easy & slow. Don't try to solve the toughest questions from day 1. You are no Einstein, or else you wouldn't have been looking for answers to the above question on a public platform. Try to grasp the topics and make them part of your life. For the first six months only read, read & read more...

After six months start solving questions. If you face any problems, read again...

Gradually move on to 
Multiple Choice Questions (MCQ or Objective) ... Develop a winning strategy which works for you. Everybody has their own approach to solving the problems of any exam or ...err life.
Which books to follow?
For Physics - H.C. Verma & NCERT are more than sufficient 

A WORD OF CAUTION : Stop reading Books which turn JEE questions into theory!
Would you take an advice from a physics faculty? 
Worship HC VERMA like Bible/Geeta/Quran .... rest will follow. In other words, understand every word, punctuation, etc. written in the book. You will surely ace the physics portion of current JEE papers
