I don’t want to Pass Exam ! No one said ever …

pass examEveryone wants to pass exam – especially when it comes to Board Exams. Many enjoyed the entire year in company with friends from the class and outside. Now the exam fever is on and some are finding it difficult to get pass marks and Physics is the one subject many find it difficult to mug up in a hurry. So, here we have come up with a sure shot method to succeed. If you are ready to work hard, you can score more than 50% marks with the method we suggest. But you should strictly follow the schedule.

 

Step #1

Make a strong determination and say aloud “I will Pass Exam”

Your decision and determination will work more than anyone else’s. The first step towards to success is to believe that you can do it and be ready to work for it irrespective of the hardships and troubles you may face during the course. Put a reminder at a visible place so that you’re always reminded of your decision to pass exam.

Step #2

Read through the complete syllabus of CBSE Physics (Class 12)

Read through the complete syllabus of CBSE Physics (Class 12) trying to remember what you have heard about it and know about it. Don’t worry even if you feel like you have never heard anything about many of the topics. Be cool and go on. PUT A TICK MARK ON THE TOPICS WHICH YOU KNOW VERY WELL (Hope that there are some portions like that. The more portions you know the better marks  you can expect. Be honest at this point)

For a quick reference I have added the Syllabus here

Nicholas James is a motivational speaker from Australia. Born with phocomelia, a rare disorder characterised by the absence of legs and arms. As a child, he struggled mentally and emotionally as well as physically, but eventually came to terms with his disability. He presents motivational speeches worldwide which focus on living with disabilities and finding hope and meaning in life.

Vujicic asked his parents when he was aged 13 about his birth. Several days before he was born, there was no notification from a doctor or nurse that something was wrong. However, when he was born his mother asked a nurse how the baby was and there was a silence among the nurses. When his mother persisted and asked a doctor what had happened with the baby, he said “phocomelia”. As his mother worked as a paediatric nurse in charge of a delivery room, she immediately knew what the medical term meant. At first, she refused to see him or hold him when the nurse had him in front of her, but she and her husband tried to accept it and tried to understand God’s plan for their son through a strong faith in God

Even though his mother gave him a cushion to support himself, he overcame and taught himself how to stand up with a method by leaning his forehead over the wall and slowly standing up. Originally, he was born with combined two toes, so he could use them for rolling over, shoving and bracing himself. Because of this, his parents and doctor decided to have an operation to separate his toes so that he could use them as fingers to grab, turn pages and other functions. Even though the operation did not go as well as the doctor wanted, he tried to adapt using these freed toes and with the help of an electronic wheelchair, computer and mobile phone became more free.

After his mother showed him a newspaper article about a man dealing with a severe disability when he was seventeen, he started to give talks at his prayer group and later founded his non-profit organisation, Life Without Limbs.

He concludes that his childhood was an “amazingly normal childhood” and he advises readers to not give up, to change their circumstances if needed and to stop their concerns about whether their luck will be better and run after any desire.

COLLECTION OF DIAGRAMS FROM MAGNETIC EFFECTS OF CURRENT FOR CBSE PHYSICS CLASS XII

magnetic effect photo-2Download the collection of diagrams from the chapter Magnetic Effects of current from the link below. Cyclotron and Moving Coil Galvanometer seems to the most important topics here. Conversion of galvanometer to ammeter and voltmeter is also to be given due weightage. Remember, the importance of a radial magnetic field in MCG (Moving Coil Galvanometer) is a frequently asked question in CBSE.

COLLECTION OF DIAGRAMS FROM CURRENT ELECTRICITY FOR CBSE PHYSICS CLASS XII

There are a lot of circuit diagrams and other diagrams to be practised from the chapter current electricity. The essential diagrams are prepared in the following file for ready use. You may take a printout of the file for practice.

When you draw the diagram, don’t draw freehand diagrams. Use geometrical instruments and pencil. The diagram should be neat and perfect. At the same time, you should not be consuming lot of time in perfecting the diagrams at the cost of answers to other questions.

In order to draw diagrams perfectly consuming very less time, it is necessary to practise all the diagrams well in advance. the file given below is a collection of all diagrams from the chapter current electricity as per the NCERT textbook.

CBSE Sample Paper & Marking Scheme for Class Xii Physics 2016 – Free Download

CBSE published sample question papers for all subject for the year 2012. You can download the CBSE  Sample paper in Physics and the marking scheme for class Xii 2016 here.

Why Practice CBSE Sample Papers and Marking Scheme?

Practising the sample question paper and the Marking Scheme will give you an idea of the type of questions  in the Board Examination 2016. It also gives an insight into “How the value points are allotted marks?” . This helps you to plan well for the exam and get maximum marks by limiting the extend of the answer and get maximum marks and save time.CBSE sample paper

 

The Sample Question Papers submitted by CBSE officially is considered very important. CBSE use to publish a set of sample papers every year which essentially reminds every student the level of preparation expected from each. It was a common practice in every school to grab copies of the sample papers published by CBSE and every teacher used to make sure that all the students compulsorily solve all the questions of the CBSE Sample Papers. Without the CBSE sample papers and previous question papers, many students simply learn by rot a few questions and answers exhibiting a dismal performance in the Board Exam. We don’t you to be a poor performer. Keep it a point that you practise all the questions from the CBSE sample paper.

So, what to do to Download CBSE Sample Paper!

Just download  and practice the sample question paper from the link below and make sure to consult whether your answers conform to the answers expected.
