Hi, Im linds and i really need your help, im having real trouble in my English Teachers, they told me that i need some help in my grammar and in spelling, hope you can help me

Thank you so much

when i am going to use has /have?

In informal English the pronoun "you" is often used to indicate an indefinite person, not necessarily the reader or listener. This can be mildly offensive, for example:

When you make a mistake....
It is preferable to use third person:
When one makes a mistake...
When an engineer makes a mistake....
Other synonyms for this usage of "you" include "a person", "people", etc.

The usage of "you" often results in childish constructions that indicate personal involvement of the reader when it is unnecessary or inappropriate:
When you apply a greater electric field....

 Hi folks! How are you all doing? First of all, I'd like to say thank you to all the wonderful people who are helping others for their English needs. 

Anyway, I would like to ask which one is correct for this sentence or statement(?) 

1.) "Give your best till the end" or "do your best to the end" 

Many thanks in advance :))
