Manage to do / Achive to get
Hi everybody!
I have doubts about when I have to use "manage to do" or "achieve to get". I think in Spanish both of them mean "conseguir hacer algo", but in what context must I use each one.
Thanks.

Question

Answer

When you say, "I managed to finish my homework/ I managed to get the keys under the seat." It means, you got it done just in time/ you were able to get the keys, it implies that it was difficult to get the keys.

When you use achieve, it means you completed or finished something. 
Ex: He achieved his dream in becoming a doctor.

I hope this helps.
