7/30/2019 Here Are Some Tips to Get 90

1/4

Here are some tips to get 90+ in Physics:

1. Solve the three official CBSE sample papers thoroughly

Doesnt need further explanations, solve them in the 3 hour time frame without looking at the

answers and check with the answers then. See how many marks you get considering step-marking

as well.

You can download these CBSE sample papersfrom here

2. Take time to absorb the marking scheme (Blue-print)

There is a very little chance that the paper comes out of the blue-print like it came in my time but

nonetheless understanding how paper will be set can turn things better for you.

Lets take up the blue-print given by CBSE and Ill explain you how I went about it during my

preparation.

Regular Order

Electrostatics 08 marks

Current electricity 07 marks

Magnetic effect of current and magnetism 08 marks EMI and AC 08 marks

EM Waves 03 marks

Optics 14 marks

Dual nature of radiation and matter 04 marks

Atoms and Nuclei 06 marks

Electronic Devices 07 marks

Communication systems 05 marks

Modified Order (As per weightage)

Optics (Both Wave and Ray optics) Electrostatics

Magnetic effect of current and magnetism

EMI and AC

Current electricity

Electronic devices

Atoms and Nuclei

2/4

Communication systems

Dual nature of matter

Electomagnetic waves

As you can see in the second column, I rearranged the topics with the ones having higher weightageon top and so on.

I started from the bottom part. EM waves, saw the chapter for an hour, left it cause I didnt

understand much of it but noted only important definitions like Displacement current, and the wave

equation.

Dual Nature of matter, along with Atoms and Nuclei were finished next. Considering my love for

Atomic Structure (From class XIth), I fairly enjoyed doing this.

Then Communication systems, didnt like the chapter, so left it for later.

Now, there was a little digression here, as I went up the list, the chapters were becoming heavier

and heavier, I had to reshuffle again according to what I knew well. I just stuck to mastering what all

halves I knew and finished them to perfection. Like Electrost atics, Curr ent Electric i ty, Magnetic

effects of cu rrentwere some topics that were there in my mind though not perfectly. I finished them

off from my tuition notes first, did 1 and 2 marker conceptual questions from the sample papers book

and solved some NCERT questions.

Then came EMI and AC. EMI is fairly a theoretical chapter with Lenz law having the maximum

amount of questions floating around. I read its theory from NCERT textbook and solved 1 and 2

markers. Now for EMI, these short questions were quite useful as this chapter has very minute

intricacies which one need to look after.

Alternating Current felt huge, and totally new. I was already weak in Waves and that carried onto

AC as well. I strategized differently for this. Did transformers, generator and their theory, working

and principle really well. I felt these were bigger birds and if they had a chance they would appear as

a five markers.

Then read about Phasors over the Internet, came back and read the chapter again. Felt a little

comfortable and finished it up though not up to the mark. Left it for sometime to settle in my head.

I was now in the final stage with only Optics and few small chapters left. ForRay optics, I read mytuition notes atleast twice. Derivations like forfocus o f mirrors and lens, the lens maker

formulawere done till perfection. Didnt touch a numerical of it till the very last day of my

examination, I felt if I knew the theory I could do the numerical as well. Didnt touch my textbook at

all for Ray optics, only smaller concise notes.

Do study optical instruments, their working and principle as they are almost sure shot every year.

ForWave optics, I read it from the NCERT textbook line by line and to tell you, YDSE(Youngs

Double Slit Experiment) is the most important thing in this chapter. If you had only one day in hand

for it,YDSE, Huygens law and Brewsters angle would be the only thing you would need to do

from this chapter.

With this, Communication systems and Electronic Devices (Semiconductors) were only left.

I somehow mugged up Semiconductors but left Transistors altogether. I knew if they were coming,

they had a higher probability of coming as five markers, and five markers shouldve an option. So, I

am almost safe here.

Communication systems made me yawn first, it made me again. I only studied the definitions of sky

waves, etc., learnt the only formula in the chapter by-heart which is root (2rH) where H is the height

of tower.

3. Underline important lines in textbook while studying

Underlining is important, as when you are done with the chapter, you just have to read the

underlined sentences to get the main gist of the chapter. Boosts your revision really well and saves

time for your girlfriend/boyfriend.

5. Get sample papers, Do them a bit

I personally brought ULike Sample papers for this job. To be frank, I never went past the 1 and 2

markers given in the book. They were plenty in number and I just stuck to those. But avoid doing

this, solve other parts as well. The more pages you do, the more stronger your preparation would be.


4/4

If youve plenty of time in hand after this, do the mock test papers.

Also, Consider allotting equal time to all the subjects, if you are acutely short on time, you may skip

doing mock test papers in exam like conditions but just skim through them once.

6. Solve last 10-year question papers

Solving the last 10 year question papers of DELHI region, OUTSIDE DELHI and other regions will

make your 90+ score sure shot. Many of the times, the 1 and 2 markers are direct lifts and you can

see there are many repetitions. By-heart the one markers if you are stuck somewhere.

7. Chillax and enjoy physics

Scoring marks is not the primary goal, read to learn about our beautiful surroundings. Enjoy the

subject, try researching on how physicist thought and deduced the laws and theorems. Then read

your text, youll find yourself enjoying the whole practice and youll get the feeling of reading a novel.
