Which is correct:

1-I can't believe that someone can acheive so much in such little time.
2-I can't believe that someone can acheive so much in so little time.

Sentence 2 is correct.

However, it could also be worded "I can't believe that someone can achieve so much in such a short time".

Note correct spelling of achieve! It follows the famous rule "i before e except after c".
