Although he studied hard, yet he failed his exams

Although he studied hard, yet he failed his exams.

Is 'yet' optional? Thanks.

No, it's just wrong.

Either, "Although he studied hard he failed in his exams."
or, "He studied hard, yet he failed in his exams."

No — it's wrong.

Use either 'although' or 'yet' — not both.

EDIT: Cross-posted with Roman.

Can I exclude 'in'?

Yes, you can omit it.
