Hi, Mmy selfname is Ravikumar. Hi, my name is Ravikumar.

“My” doesn’t need to be capitalised because it’s not the start of a new sentence. You could either say “my name is” or “I am”

Hi, My selfI am Ravikumar. Hi, I am Ravikumar.

"I" instead of "My"

Hi, Mmy selfname is Ravikumar. Hi, my name is Ravikumar.

Missing “is”

Hi, Mmy selfname is Ravikumar. Hi, my name is Ravikumar.

I'm here to learn English. I'm here to learn English.

To further clarify, you could say, “I’m posting here to better my English.”

In the form og writing and speaking , could anyone assist meCould someone please assist/help me with writing and speaking while I am doing some tasks. Could someone please assist/help me with writing and speaking while I am doing some tasks.

You don’t need to say “in the form of” - you can just say “writing and speaking” and people should understand it. It sounds more natural to specify “writing and speaking” later in the sentence. “Someone” sounds better than “anyone” here, but I don’t really know exactly why. I added in “please” just for politeness, but grammatically speaking, it doesn’t really matter too much whether you use it (but for more polite and nice interactions, I’d recommend it). “Help” is more commonly used. “Assist” is reserved more for very formal speech, but it’s still grammatically correct. Alternatively, if I’ve understood exactly what you meant correctly, I think you could also say “Could someone please help me with some writing and speaking tasks/activities?”

"of" instead of "og", no space between "speaking" and the comma (,) and use a question mark, "?", at the end of a question.

Misspelt “of” and no space before commas. A more natural way would be, “Can anyone give me tips for my writing and speaking?” This is a question, so you need to include correct punctuation. I would suggest reading other posts online and their corrections. With speaking, focus especially on how vowels sound.

not sure what you mean by 'tasks'

It willould be a great help to me. It would be a great help to me.

Just a nuanced meaning here, but “will” implies that it is certain that someone will help you. However, since you were asking for help, “would”, which expresses a hypothetical situation in which it’s not guaranteed that someone will answer and help you, would be the better option in my opinion. “Will” still works well though so this is more of an optional suggestion. Alternatively, you could also say “it would help me a lot”, which is what I would probably say, but that’s also just a matter of personal preference.

It will be aof great help to me. It will be of great help to me.
