If you are planning to appear for JEE 2011, spend April 2009 in having some relaxation from your X class examination effort and in revising your X portion. If you revise your X portion once again and start learning XI portion from 1 May 2009, you will be able to grasp the subject much faster due to the continuity that you are maintaining by revising your X portion especially of chemistry, Mathematics and Physics. Plan to spend aroud 5 to 6 hours on revising your X material. Plan to complete a quick review of every chapter in X class and remember important concepts. It is not difficult to recollect important points as you have written the examination recently. With some slight effort you will be recollecting a large number of concepts.
I am preparing study guides for each chapter of Chemistry, Mathematics and Physics to provide you a daily plan of study and problem solving that will help you to complete the entire XI portion related to JEE by 31st December 2009. From January you can focus and prepare for Board examinations or school internal examinations with revision and solving some test papers at JEE level up to 30th April 2010.
