Guidance in Physics for XI, XII, ISEET & NEET-UG
Success is not a matter of luck or genius. It depends on adequate preparation and indomitable determination.
Physics cannot be learnt by rote. It has to be read, understood and digested.
Any subject can be mastered by using 3 basic principles of psychology:-
So here I am giving you a method which I have come to, through trial and error and through my past students who have been highly successful.
Physics, consists of :-
How to master these?
1] Definitions:- Read, understand, practice thrice (orally)
2] Diagrams:- Observe, practice thrice (written)
3] Explanations:- Read, understand, practice twice (orally)
4] Derivations:- Read, understand, practice thrice (written)
5] Problems:- Prepare a list of all the formulae and glance through them everyday while brushing teeth, having tea or any other activity during which you cannot devote full attention to your studies.
Well, you may feel that this will consume a lot of time. But it is not so. Practice will make you perfect and fast.
Marking scheme (Theory)
Section I ----- 35 Marks
Section II ----- 35 Marks
Single paper of 70marks
SOME TIPS FOR PHYSICS THEORY EXAMS
1] Prepare the portion thoroughly well. Writing practice should be done as much as possible. This will greatly improve the writing speed and correctness of solutions in examinations.
2] Make a proper choice of questions. In theory, those questions whose answers are very lengthy and time consuming should be avoided. Those Problems which have lengthy solution or too many calculations should be avoided.
3] Attempt those questions first for which you can write answers in an impressive manner.
4] Answer for new question must be always started on a fresh page.
5] All sub-questions should be attempted together as far as possible.
6] Some extra sub-questions could be done at the end, if time permits. For this purpose, spaces should not be left in between.
7] For calculations, use only logarithmic tables.
8] Do not overwrite.
9] Draw your diagrams neatly and label them properly.
10] Underline the important points in an answer.
11] Put the formula of a numerical problem in a separate box and underline the final answer twice.
12] Titles and sub-titles should be given wherever possible.
13] Numbers of questions/sub-questions must be marked properly. If not done so, it may considerably irritate the examiner, which could result in deduction of your marks.
SOME TIPS FOR PHYSICS PRACTICALS & ACTIVITY
Make jottings (circuit diagram, formula, observation table, expected result, etc) on small chits of papers for each and every experiment. Glance through these chits as and when possible everyday. Especially the circuit diagrams should be observed carefully since you are likely to get confused with them.
Practicals : 20 Marks
Activity : 10 Marks
Total : 30 Marks
Marks Distribution For Each Experiment :
A certified journal will fetch you 2 Marks.
Activity : Marks distribution not finalised
What to do at the practical examinations:
The moment you reach your table, read the question slip on your answer paper carefully. Have a look at the apparatus, which will refresh your memory.
Presentation of the performed experiment should be in the following manner:-
Aim: You will get it from the question-slip itself.
Apparatus: The instrument, etc. that you see on the table
Diagram: Draw the diagram (if required) with pencil. For electrical experiments a circuit diagram is a must. Also show the direction of the flow of electric current. Get it checked by the examiner (a must). Connect the circuit and get that too checked by the examiner (a must). For light experiments show the direction of the ray of light.
Formula or Law: To be remembered through practice
Observations: The observation table has to be drawn with a pencil and the observations to be written with ink or ball point pen (blue or black only). Show the very first observation you take to the examiner (a must). The examiner will then mark that observation. Once you write your observations in this table do not cancel them as far as possible. If however you have to cancel an observation then take the examiner’s signature at that place.
Graph: (if required) has to be drawn on a graph paper with a pencil. Do not forget to write the scale used for the graph. Also remember that the intervals on an axis (X or Y axis) should be equal.
Calculations: should be presented as neatly as possible. If presented in a table format it would look the neatest.
Result: Do not forget to write the results. Also do not forget to write the units since they carry marks.
Precautions: Write at least two meaningful precautions.
Well, now that you know how to prepare for and write your Physics theory and Practical exams, what you need is a good temperament at the time of the exams, which will naturally come to you if you are well prepared.
Friends, have a healthy attitude and you will flourish in whatever career you choose. Look not for others defects, but strive for your own improvement.
