How did ur preci go?
@all
Share your preci please
I'll be sharing mine shortly

I did forward it to her and she said it was not the case of parallelism and changing sleeping bag to a bag just won't do. I also forwarded what Qublai Khan was suggesting, that is the article thing but that is not the case either.
Serial comma is the issue. First it is a US thing which British system avoids. If we really really have to use comma then it must be to avoid confusion which is not the case with 3 distinct objects here.
See this is why we are fretting over style guide. Things acceptable in one style guide are a no, no in another.

And there's nothing I can do.

Thanks for the compliment. I don't know why me, though.I would tell you to raise your standards but that will make me sound like a jerk.
Jokes apart,
Sorry for being late!
It is oxford comma. Personally, I like oxford comma. It makes thing clearer, nicer, and easier.
See, what I did there!

I knew it was right, but as they say in boxing,sometimes you gotta roll with the punches. So, I removed it for FPSC's sake.

The article is fine people. I don't even know what is anyone implying about article or how could it be changed at all.
And it can't be parallelism because:
Sleeping bag is a noun. It is a singular noun and sleeping does not define the bag.
I will wear my gown to the party. (Yayy!)
I will wear my nightgown to the party. (What?)

I think, style guide will not do you much good, because FPSC is not as organized (read: at all).

If you are still worried though.
I will suggest you punctuation related books which are fun as well.
"Eats, Shoots, and leaves"
"Confessions of a comma queen"
and the evergreen,
"Elements of style, by Strunk and White"

All the best for future.
P.S: @All:
That's my advice, based on take it or leave it basis. I will not provide any links as I have mentioned books and I don't trust websites.

For the sake of your clarification I'm explaining you, and I hope you will learn this.My last and final verdict.
Do ask here,how many types of errors exist in a sentence?
Yes,comma splice and fused sentences are linked up with wrong punctuation mark, but it has no link with oxford comma.
Secondly,Britishers itself would rather prefer oxford comma, because it listify the things appropriately, only point of contention is obsessive usage. It is permissible in every form of writing except the one in which coma is creating redundancy.
.
Even Britishers also use it.For example Cambridge.
This comma is not used to avoid confusion.This comma is a must before coordinating conjunction.Do tell the teacher that oxford comma is also used before FANBOYS(for,and,but,or,yet, and so).Notice how I used oxford comma in brackets.It doesn't deslistify, but creates a smooth flow in the categorization of same things.
.
Already explained oxford comma will also create problem with so and or as well.
Regarding my correction,I consulted,what we have found is a problem of sentence parallelism not comma splice error.
The strong point in my argument is that my error do exist and weak point in your argument is that oxford comma is not error,but linked with style of writing and grammar works on standard principles,which has departmentalized the type of errors. Please read the types of error in a sentence.(with open mind and without any external influence,even of mine)
You will find many technical things.
I hope you have learnt it.Another news,the paper setter is also following APA style of writing.For example,Precise and composition as well as the explanation mention at the start of paper.
For example I have written the title of precise like
Cherokee: A Memory of Pristine Indian Civilization
Note: I've capitalized each word in the title but not preposition,a characteristic feature to identify the style of writing,because we are encouraged to use capital letters for all words except preposition.
Now,collect evidences from precise by keeping this assumption that if I were an examiner than definitely I will choose a paragraph,where I my expertise are self evident.(which in mine case is APA)
I hope it worked.Lastly ,what's your mentor expertise in the field of Linguistic.I have taken ESL classes.
@Nzish
I know you are very smart,but please don't lambargast in the absence of any proof.Like,What do you know about the paper setter as well as examiner!
Nothing,and I believe that its not rocket science to learn such errors.Dddd
Do you people believe that I just prepare for CSS in 3 months only.At least examiner has experience which is at least missing in my case.
I hope k Tom is mrtba naraz nhy ho g.

haha yeah. Good one.

Yeah I am beginning to see this as well. I guess nothing can be done over it.

Eats, shoot, and leaves is one of my favorite grammar books. I like how it presents things in an easy way. I read it last yr, I need to re-read it.
Others I have no idea about so I'll check those too. Thank you for suggesting these.

@Ursula
She is British and after reading this paper and specifically this sentence she asked me about style guide saying that although Brits avoid serial comma generally it is not that uncommon and even in Britain they follow style guides of the institute they are working in. So there are various styles and you mentioned one of those.
Finally some style guide name to forward to her.
She is a British English teacher. I got to know her from my brother and now I kind of study online from her. Don't ask why not here and all, long story. Also we haven't figured out what and how we'll conduct our correspondence so these days I struggle to present FPSC in good light to her because well she is a foreigner. I figured, for starters, I shouldn't bad mouth FPSC. She googled and God knows why stumbled upon Pakistan Post's official website. She was disappointed that the site had many grammatically incorrect posts. I was this close to congratulating her for visiting that site because reading their posts aside, we don't even visit their site. lol
WOW! Really! Awesome. I am telling myself to not take it lightly now.

As per your long description, I still don't agree however let's drop it now. I don't think either of us will change our point and since it will turn into an argument rather debate, it won't help any of us. Languages are never governed by laws, like cultures they expand, contract, merge and get changed. There is a reason we have many linguists still arguing over apostrophes and commas. So personally, we all could be right and all could be wrong.
Now if only examiners were like me. haha.

Let's put the case in frozen ice, because its useless to elucidate further at a point, when even not a single inch progress is made.That's happened first time in my life.Because this time it was my beloved Pakistani.Keep your spirit high and my all best wishes are with you.

I am not the only one here you failed to convince but lol thanks for the attention.
Thanks for the wishes. Good luck for papers. Keep rocking!

I hope,you people make my misconception clear in that case.I desperately wanted to learn, because through this point my thousands of other points would be cleared.
Come on! we are not going to debate,though i love it,but please elaborate me further.
I'm here on this forum only to learn from my mistake.
Let me remind you
I will not fear mistakes:i will reflect and learn from other
my motto and my passion of life.
A beautiful message given from my mentor to me.As she also said that it is against the dignity of mankind to surrender.
P.S. i dont want to be rocked i just want to learn and for this purpose i am ready and i'm at ground zero potential.

in this case the fpsc recommended book should be downloaded and studied. Recommended book I think is read better write better.
