Hi I have a question.

For my evidence for section B I have cropped my screenshots

Is it alright just to say what page the screenshot is on?

Thanks

You could well lose marks. The marker may find it difficult to find the evidence. If they cannot find it then no marks will be awarded.

These markers dont get paid much per paper so not many of them will be conscientious enough to look for the evidence thoroughly if you have failed to properly display the location of each feature.

Your best bet is probably to say the page number and draw a box around each relevant cell or feature which you have talked about in your answers

Thanks for this

By this do you mean circle it on the evidence sheet?
If so, I won't be seeing the evidence sheet again before the exam, so can I do this in the exam?

Thanks again

Hi I have a question.

For my evidence for section B I have cropped my screenshots

Will I loose marks in my answers for not naming what cell the sum is in for example

Is it alright just to say what page the screenshot is on?

Thanks

Thanks a lot this is such a good idea! Should everyone make a mock exam for the predictions?

Hi, i have a question regarding AA923's predicted questions mock paper.

for part "(b) Encoding value judgements from a questionnaire can often lead to inaccurate results. Explain with the use of two appropriate examples why this may happen. [2x2]"

Could you please provide an answer for this as i have no clue how to answer this particular question especially the examples.

Thank you!

Can some amazing person please explain to me all the things about web pages. Like Hyperlinks/ Frames and all them
Also I don't remember doing HTML and all that in class so could you explain these.
Thank you!

Hyperlinks - These are objects/text which when clicked upon take you to another file, image, or a different part of your current presentation. (1 mark)Could be used in the tutorial by clicking on an object/text to take them to an online demonstration of some feature. (2 marks)
Frame - A Frame is a section of a webpage in which semi-independent activities can take place. (1)Suitable example e.g. an area with a menu or group of links. (1)
HTML – Hypertext markup language is the programming code used to make the page and will contain details about fonts,colours, tables and images used.
Advantages of HTML:
Can placegraphics more accurately
Can have more control over the layout / allows better customisation
Likely to takeup less memory / less demanding on the system
Loads fasterthan using a template
Compatibility -enables to be displayed on a number of different platforms
Animation – Creating a key frameanimation which loads very quickly when visiting pages

Thanks! Are these the 4 that we only need to know for WJEC??? Or are there others
