Made Few mistakes in form , can there be a refusal ?

I have applied for naturalization last week but i am stress if can there be a refusal can somebody please advise from their experience

1. Forgot to mention i am also a director in 2 companies currently ( no income taken just director )

2. I wrote the names of 2 companies i worked from 2008 to 2011 ( i was student back then ) only worked part time less than 20hrs maybe few months but mentioned i worked whole 3 years as couldnt remember the dates hmrc query wont bring any record if any as those companies were dissolved as well and i was allowed 20hrs back then

3. my student visa was refused in 2010 and i was on appeal which was refused as well and went for higher court appeal during which i got visa it was minor refusal for maintenance fee .

Please if somebody can advise are these points lead to refusal

I am still waiting for any answers or suggestions , if i can contact Home office and let them know about the mistakes any admin or experts can reply me plss ???

Write a concise letter setting out the details - quote your reference number (wait for it if you still haven't got it) - attach documents if any. Keep copies of everything and send by signed-for post. Errors do happen. Point 3 may be an issue but I couldn't give you any assurance. But better to disclose than being refused for not divulging.
