After saving, updated right order appears on the screen.

After clicking SAVE, the choices filled are updated as shown below WITH A MESSAGE.


Close the box to see new preference list (see below):


Click Multiple Deletion to delete more than one filled choices


You can check all or check only the selected choices to delete from the list



These options will be deleted from your choices list and the remaining choices will be
automatically reordered as shown below:

Hey future IITians and NITians. JEE Main 2015 is nearing. Here are few tips to follow before the exam and while writing the JEE Main examination.

Health is Wealth

Sleeping boy

While preparing for JEE kind exams, students often stay awake until midnight and study. It may help you in your preparation. But in long term, it affects your both physical and mental health. Being deprived of sleep, students lack concentration and lose their ability to think when it matters the most. Make sure you sleep for at least 6 hours a day. It refreshes your brain for another day of brainstorming.

Healthy food image

Avoid eating outside and junk foods a week before the exam. As summer is getting hotter, you need keep yourself hydrated. Make sure you drink lots of water and other natural sources like coconut water, fruit juices, etc. Before going into the examination room, drink some water. Dehydration can cause dizziness.

Exam Preparation

exam writing

Don't postpone any topic or chapter to be learnt on the day before the examination. Keep the last day for revision of formulas and concepts.

exam writing

Solve a model paper which can help you grow in confidence as well as getting you acquainted with the examination 'mood'.

Exam hate

If you are weak in any particular concept, don't try to learn or understand it the day before examination. You may get one question or no question at all from that concept. Instead of wasting time try to learn that, revise the concepts you know well and solve a problem or two.


on time

Visit the examination centre an hour before the exam or you may miss some important instructions.

While writing examination

Exam Panic fear

Don't 'panic'. Its the last you'll ever want to do in a competitive exam. Even if you cannot solve 4 or 5 successive questions, don't panic. Easy questions are out there waiting to be solved by you.

exam

Start with the easiest subject for you. If you think a question will consume a lot of time or difficult to be solved, leave it for the last. Don't waste your time. Speed is very important for JEE. So don't sit on question which troubles you.

OMR shading

Don't leave the shading of ORS to the last minute. Start shading the OMR half an hour before the completion of alloted 3 hours.


Be confident!


Avoid the fear of exam. Some students have fear clinging on to them the moment they step inside the examination hall or get the question paper.


Believing in yourself is the most important thing you need before an exam.

 Best of Luck

Chemistry is one of the subjects where there is lot to memorize. Not only some formulas of Physical chemistry but also some facts and figures in inorganic chemistry and some chemical reactions, reagents used and their mechanisms in organic chemistry. For last minute revision reading the whole chapter or syllabus again is not advisable. You need a formula booklet where you can find all the formulas and key points. Below, I give you a Chemistry formula booklet which you find useful for revising and reference.

JEE Main is easy to crack if you follow a definite strategy. All it requires is a little hard work and wise planning.Students are often concerned over their preparations for JEE examinations and most of the students are pessimistic of the results. Lack of confidence causes tension during exams which results in bad scores even though your are capable of scoring good scores. Below I have given some tips to follow while preparing for the JEE Main 2015 which will enable you to score good marks and boosts your confidence.

dc pandey optics and modern physics solutions


Optics is one of the most important chapters of IIT-JEE physics. Once you understand the concepts even advanced problems will be easy to solve. Even though Modern physics is not important for JEE Advanced, its an easy way to score about 15-25 marks in JEE Main. You don't need to understand much in Modern physics - just formulas and other memory stuff.

About the book 'Understanding Physics for JEE Main and Advanced Optics and Modern physics':

Understanding Physics for JEE Main & Advanced Optics & Modern Physics is a comprehensive book for students preparing for various engineering entrance examinations. The book comprises of chapters on electromagnetic waves, reflection of light, refraction of light, interference and diffraction of light, and semiconductors. In addition, the book consists of several solved and unsolved multiple choice questions for thorough practice and revision.

Here I've posted the solutions for problems in 'Understanding Physics for JEE Main and Advanced Optics and Modern physics' by DC pandey.
