The verb SUCCEED (réussir à faire)

Because in French we say "réussir à faire" and "réussir" = "succeed", I hear a lot of people translate that expression to "I succeeded to do". But actually there's a nuance. 

First of all, "succeed to do" is grammatically wrong, because "suceed" is followed by the preposition "in" and then by a gerund ("ing"), so you would have to say "succeed in doing". 

That's for the grammar, now for the nuance. If you pay attention, you'll see that this expression isn't that used in English by natives, and we often use "manage to" instead, for example: 

• I managed to do my homework all by myself
• Did you manage to finish the exercise? 
• There was a lot of traffic, but I managed to get to the meeting on time.  

First, "succeed in" is a slightly more formal alternative to "manage to". 

And according to thisvsthat.io, this is where the real nuance is: 

"manage to" implies overcoming obstacles or challenges in order to accomplish something, while "succeed in" simply means achieving a desired outcome. "Manage to" suggests a sense of determination and effort in the face of difficulties, while "succeed in" focuses more on the end result. Overall, both phrases convey a sense of accomplishment, but with slightly different connotations. 

 The BBC says 

"Manage to" is used in a particular situation or are referring to a specific achievement.

manage = succeed / cope: 
We use the verbs manage to and manage a great deal in current English when we want to say that we are able to cope with a difficult situation or find time for a particular task. Compare the following:

• It was very icy, but I managed to keep the car on the road.
• Veronica was very upset when Ben left her, but she managed to smile nevertheless.
• She didn't really want to go to Mexico, but Tony managed to persuade her somehow.
• Can you help me put up my new shed? ~ I can manage a few hours in the morning, but I'm busy in the afternoon.
• This is an ideal job for those who can only manage a few hours each week.
• Can I give you a hand with that? ~ No, it's all right. I'll manage./ I can manage.

I think the best is to just try to use "manage to" by default, if you're looking to really be fluent and sound native-like. If you find that task too difficult then I suppose you can keep the use of the verb "succeed" but then you have to use it correctly: with "in -ing". 

To practice using "manage to", as well as "could" and "be able to", I recommend doing unit 26 of English Grammar in Use. It's very informative on these 3 more frequent expressions.
