1) The first doubt I have is in this sentence:
I want to confirm both the classes on Monday and the ones on Tuesday.
Is it correct to say this or would it be better saying...?
I want to confirm both Monday classes and Tuesday ones.
2) The second doubt I have is in this sentence:
Can you tell me where the classes are to take place?
Is this construction correct? Or is it better to say:
Can you tell me where the classes will take place?
Thank you verry much.
