Hi,

Both are acceptable but remember the comma after ‘mistake’ and remember we ‘make’ mistakes and do not ‘do’ them.

but remember the comma after ‘mistake’ and remember we ‘make’ mistakes and do not ‘do’ them.

yes, sorry

Thanks for the answer

When to use progressive and when to use will ??

And excuse me , Is that in grammer books ? Because here In Egypt we study the very formal English not the language you speak and I sometimes found that things you say is acceptable while it is not considered right here at all

for example I had a “choose” sentence between using “If I do…” and " If I have done>>"
