how to use "end up" to talk about achievements ?
I want to use "end up" with better grades or higher grades or better results/performance..I'm looking for the collocation meaningful to a native speaker

Do you want examples of how to use 'end up' with 'good results? Such as:

If I train really hard this week I will probably end up winning the contest.
If I practise English every day, I will end up being able to speak it very well.
