To people who english is the first language,
Do you still have problem with ( or make mistake in) spelling and grammar in your writing although english is your first english?

To people who english is the 2nd language,
Do you use any softwares or tools to help you improve your writing?

i got lots of comments that complaining about my spelling and grammar. I have used some software like grammaly but many mistakes it doesn't pick up. Any advices PLEASE.

THANK YOU EVERYONE.

English is my first language, and I often have to write in a foreign language for my research so I can understand how you are feeling. The reality is that it's extremely difficult to achieve native level proficiency to the point of writing perfectly correct language for academic purposes. It's possible to get close, but there will nearly always be mistakes (in my opinion). And of course, even native speakers make mistakes!
My suggestion is to find an academic in a similar field who is a native English speaker, but is trying to learn/write in your native tongue. Then you can exchange papers for proof reading/corrections. Of course, you will have to check your institution's guidelines on proof reading as some do not allow this kind of exchange and you could end up in a lot of trouble if they don't allow it.
The important thing is to remain calm and work away at your language skills as far as you can.
As a side note, typing in CAPITAL LETTERS in English is considered by many to be shouting, and should be avoided at all costs :-)

English is my first language and I have no problems when it comes to writing. Most native speakers however will still struggle to write academic text.
It must be a complete nightmare having to write in English when it is your second language.
I've noticed that one of the major giveaways that someone is not a native English speaker is their use of the words 'a' or 'the'. Learning the basic syntax of English is hard enough but learning how to use those two words can be baffling unless you've grown up with it. It's rare to find a native speaker who would struggle with them though.

I am not a native speaker and I did my PhD in English.
I found that my writing improved by reading! I read a lot and not only related to my research. I think it helps to get a grip of the language. Of course I still make mistakes and I cannot use the language as a native speaker, but I have improved a lot

Everybody makes mistakes in academic writing. Even my supervisor proposes language changes to my work which are wrong! If you want to improve your language quickly you need to immerse yourself in the language, switch all your devices to English, communicate with your friends in English, read the news in English, watch TV in English, and listen to English language songs. Also try to socialise with colleagues at university who do not speak your first language.

Thank you everyone. =)
