no, not mandatory

but when logged on as info1, the full schema info. has to be supplied

this works too:
alter session set current_schema=info;
select * from test;

It is certainly not mandatory to create a synonym when granting permissions to other users. However, it can be beneficial in many cases. For example, say there is a schema called project_fiscal_year_2018  that contains a staging table named input_data_2018 that has been granted access permissions to other users. If the five other users only need to get certain records, they would each have to select from project_fiscal_year_2018.input_data_2018 with the fully qualified name. However, creating a synonym for that table with a name like stg_2018 would make things a lot easier.

Synonyms and grants are two different and independent things.  A synonym just provides a shorter way to refer to an object.  Instead of having to use the full "owner.table_name" syntax, you can simply use the "synonym_name" to refer to the object the synonym points to.

But, without a grant, a synonym doesn't help you.  If you don't have a grant, you can't do anything with the object even if a synonym allows you to refer toit.
