السلام عليكم و رحمت الله و براكاته
I have bio practical exam after tom
Did anyone get an A if so can you give me tips so I can get an A and is it really hard to get an A as they say

 

[wizzzzzzzzzzzzzzzzz]

Btw do u rrmember p22 questions

 

[mariiqur]

Waalikumasalam warahmatuallah wabarakatuhu

I did not get an A yet.
But I think I can give you a few tips.

First things first,dont forget to say Bimillah. Read the question carefully.
Try your best not to panic.
There are always questions that you can do without carrying our any experiment if you can then do these first.
Also they usually have a graph that you need to plot.Make sure it is neat,has scale mentioned for both axes clearly.Include the labels on axis along with appropriate units.
When solving questions related to magnification be sure to put the correct units.
For observing your result you need to make a table,draw the table before starting the experiment.

Nice inshallah we will do good
Btw did u take p22

In sha Allah

Btw do u rrmember p22 questions

question 2 part b i

The question looked familiar because I asnwered someone else a few months ago, so I'm just copy-pasting. (Sorry if it isn't exactly the same )

Whenever there is a question like this, the small width lines are the eye piece graticule. The bigger lines are the stage micrometer.
Step 1: 1 eyepiece graticule unit = 0.01 divided by 4 = 0.0025mm
(this is because I know one width of stage micrometer is 0.01mm. I can SEE that there are around FOUR eyepiece graticule units that fit into one of these stage micrometer line gaps)

Step 2: 0.0025mm multiplied by 1000 = 2.5 micrometer.
(just conversion piece of cake )

Which question is this?
Thanks though.

Sorry the numbers are different. Here's an edited version:

Whenever there is a question like this, the small width lines are the eye piece graticule. The bigger lines are the stage micrometer.
Step 1: 1 eyepiece graticule unit = 0.1mm divided by 25 = 0.004mm
(this is because I know one width of stage micrometer is 0.1mm. I can SEE that there are around TWENTY--FIVE eyepiece graticule units that fit into one of these stage micrometer line gaps)

Step 2: 0.004mm multiplied by 1000 = 4 micrometer.
(just conversion piece of cake )


The previous answer was the answer to variant 3 instead:

Have a look and see if you can do it

I got it Alhamdulillah.
How many marks do we loose if its not exact?

Maybe a mark or two.

You should be attempting full marks though

TWO...scary!
I did this question and I got like 4.2 instead of 4 :/ but in that teacher did give me marks.
In sha Allah.
Pray for me.Im tensed about the microscope part!

Actually if it's just the numerical error it should be a mark only
May Allah help you. It'll be easy In Shaa Allah.
Manage your time well. Don't Panic.
Plz pray for me as well I'll pray for you

Microscopes are not too difficult. There's drawing. Labelling. And the theoretical part:
