In parts,a,b and c, in each question i would write "rounded to" instead of "to". For example, "66565 rounded to the nearest 10" instead of "66565 to the nearest 10". I just think it reads slightly better.
Part a) i) You say "the following digit is 5, so we round up, increasing 5 by one, becoming 6.", but i think you meant to say "the following digit is 5, so we round up, increasing 6 by one, becoming 7."
a) ii) I would say "Look at digit 5 in the hundreds column", instead of "Look at digit 5", in case the student gets confused with the 5 which is the last digit.
iii) Same as for ii)
v) I don't think the 9 needs to be in brackets.
ii) and iii) I would write "The" at the start of each sentence.
In the opening paragraph, i would write "up to the nth number of places" instead of "up to nth number of places".
iv) I think there should be a space between "7and" and "is5". I would also put "These are our 4 significant figures" at the end of the sentence, after you have finished all of the rounding.

In the advice you say '295 rounded to the nearest ten is 300 and NOT 2100'. I don't think this is a common mistake! I would remove this line and instead explain that sometimes the nearest ten is also the nearest hundred. You should add an extra question at the very start where the nearest ten is not also the nearest hundred.
When adding subparts to questions, you don't need a full stop and a parenthesis. Just use the parenthesis.

Error in variable testing condition
There's an error in the condition you specified in the Variable testing tab. Variable values can't be generated until it's fixed.

Test that the marking algorithm works
Check that the marking algorithm works with different sets of variables and student answers using the interface below.
Create unit tests to save expected results and to document how the algorithm should work.
There's an error which means the marking algorithm can't run:
Click on a note's name to show or hide it. Only shown notes will be included when you create a unit test.
No unit tests have been defined. Enter an answer above, select one or more notes, and click the "Create a unit test" button.
The following tests check that the question is behaving as desired.
This test has not been run yet This test produces the expected output This test does not produce the expected output
This test is not currently producing the expected result. Fix the marking algorithm to produce the expected results detailed below or, if this test is out of date, update the test to accept the current values.
One or more notes in this test are no longer defined. If these notes are no longer needed, you should delete this test.

In order to create a variable replacement, you must define at least one variable and one other part.
|Variable||Answer to use||Must be answered?|
The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:
These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
This part can't be reached by the student.
Add a "next part" reference to this part from another part.
None of the parts which can lead to this part are reachable either.
