Calculate hybridisation of an atom, Chemistry

I want to know how to calculate hybridisation of an atom in a given compound like I want to calculate hybridisation of Boron & Oxygen in this boric acid compound H3BO3 I even want to know any simpler easier method to calculate fast.

Ans) The formula for boric acid is H3 BO3
To calculate for Boron:-
as it is the cental atom...
No of valence electrons of all atoms:24
no. of octets:24/8=3
lone pairs=0
Hence the Hybrid state of Boron is sp2.

For O...
Drawing the srtucture of H3 BO3 as the central atom...
we get every O has one double bond and one coordinate bond.
Hence it has only one sigma bond so it does not enters a hybrid state
