Biology; Chemistry; Physics: Post your doubts here!

[Dark Destination]

Physics is that one subject which has this property; you solve the entire paper expecting full or an A*, and when it gets checked, you go like 'wth', cuz you end up with an A or B. But when you look at your errors, you go like, 'That was soo simple'

It's unexpected. Sometimes you expect a bad grade, and end up with something good.

Does putting up an Einstein avatar help you in this

No, but understanding his words does.

 

[Awesome12]

No, but understanding his words does.

I think the trick in MCQs is constant rechecking and full focus. What to you think?

Knowing the entire syllabus first.
Then, yeah.. Focus is important!

And instead of blindly ticking one option, its better to picture everything. Imagine the question in your mind.
Think of it as a story. Try to deduce what the examiner wants. Understand the examiners thoughts.
Capture his thoughts.
And try to deduce the answer.
Our mind is way more capable than we think. We don't even use 0.1% of it. That's what scientists say.

Rechecking. People recheck, but still lose marks. So even that's not the important thing.
But it's good to recheck, helps find the mistakes.

Oh i get it now

If s3 is close then this will happen

i only see arrows
where is specificity people -_- !

 

[Karim Nabil]

Lol, dude. If all questions were easy, that would be no fun. xD

i agree you
give that man a cookie

Current is inversely proportional to Resistance.

Okay, ICT-Master. Thanks.

Arrows show the direction of current. For current to be 'resisti-fied' it has to pass through a resistor

 

[Karim Nabil]

Okay, ICT-Master. Thanks.

hhh, you're most welcome

 

[FLRNAB]

can you be more specific?

What?

This is what the examiner report says

Question 29

This was a difficult question. A significant minority gave answer A. This answer assumes the resistance of
two 3.0 Ω resistors in parallel can be obtained by addition, which is not correct. Two resistors of resistance
3.0 Ω in parallel have a combined resistance of 1.5 Ω. The effect of switch S3 was widely recognised.

Electrons will take the path to flow which is easiest. They are like us. Would you drive in sand or on the road to the same destination?
Resistance path is ignored if there is an alternative easier path. That is the effect of switch S3.

Thanks, I got that.

That's my explanation.

There is also the method of cancellation and odd options.
If you know that some options don't apply to the question given, then cancel them and hopefully you arrive at the answer.
For the odd options I have seen that old papers would have 3 options of same property and 1 odd option, that would be the answer.

 

[FLRNAB]

That's my explanation.

You didn't "Invent" it. Did you?

I did, lol. :3

The papers were really easy back then.

 

[FLRNAB]

Much harder. See Maths papers.

I did, lol. :3

I think it was Georg Ohm. As resistance SI Unit is Ohm so he discovered it's properties.

Who are you kidding? You haven't even done O Levels.

Ikr. :'(

This is the easiest part of your life actually. Make it count.
