는 marks 친구 as the topic of the sentence.
So 친구는 means something like:
- as for my friend
- my friend, ...
- speaking of my friend, ...
It does not necessarily mean strong contrast here, although 는 can sometimes suggest contrast in other contexts. In this sentence, it mainly introduces who the sentence is about.
A very natural English-like way to feel it is:
- My friend got a scholarship this time because their grades were good.
Korean often uses a topic marker where English would simply use the subject.
Because 좋다 is a descriptive verb/adjective-like word, and with 좋다, the thing that is good is usually marked with 이/가.
So:
- 성적이 좋다 = the grades are good
- not 성적을 좋다
Here, 성적 is not a direct object. It is the thing being described as good, so 이/가 is the natural particle.
This pattern is common:
- 날씨가 좋아요 = The weather is good.
- 기분이 좋아요 = I feel good / My mood is good.
- 성적이 좋아요 = The grades are good.
