Hi, It's all are useful!

Thank you!

I studied enough but I'm really confused when I make a sentence to say.
I'm not sure when  I use should or have to or must.
So I want to know difference. Please help me.
For example,                                                                                                                 
1. We have to meet at 6 o'clock at the station.                                                          
2. You should get up early than before.                                
3.  I'll have to look at my phone(Series 01 Episode 06)

excellent bhia ...!!

I liked this article very much. I's  very helpfull.

So, if I said:"You must see Serbia, it is beautipful countre!", I am not mam in your head, but I am very polite...

I don't understand something. If I say "you must come to see me", is this sentence more polite invitation than "would you like to see me".
Thank you

Hi Harmonious
in the sentence "you must come and see me" (better than "you must come to see me"), the modal must is used for emphatic invitations or strong advice (the sentence means: I'll be really happy if you come and see me"). For example: you must read this book / see this film, and so on (the book is very interesting, the film is really fun).
I think the sentence "would you like to see me" does not make much sense.
You could say: would you like to play with me?, would you like to dance with me?, and so on. You use would like + infinitive as a polite way of saying "want" (I want to invite you...).
Hope this helps you.

I badly need your help.
When talking about school rules is it better to use MUST or HAVE TO?
For example: Students must wear uniforms. / Students have to wear uniforms.
Students must do their homework. / Students have to do their homework.
Students must be on time. / Students have to be on time.
And what about speaking in the first person?
Is it better to say: I must be on time (at school), or I have to be on time (at school)?
Help me, please.
Thanks a lot.
