1. Have you received the prizes so far?
2. Have you ever received the prizes.
(Are both the same in meaning, showing 'experience'?)
3. Have you ever received the prizes so far?
(Can we say like this, Sentence 3? Does Sentence 3 have the same meaning as the others?)
In #3, you need to remove either "ever" or "so far." You don't need both; they are redundant.
#1 and #2 don't mean exactly the same thing, but they're close. I think #2 is the best of these 3 sentences.
Yes I Have Received Prizes
