It obviously matters depending on the subject you're applying to grad school for.
I'm saying it seems like it doesn't generally matter,say if you are going into atmospheric physics,whether you've taken GR vs quantum optics in undergrad.
On second thought,it may have been a silly question.
It is not a silly question, but you've given us a silly scenario.
The reason why I asked if you have discussed this with your advisor is because there are OTHER surrounding information that are as relevant as what you intend to do. Here's the scenario:
rockyleg: Hi Prof. ZapperZ. I have a question. Do you think I should take the GR class?
ZapperZ: It depends, rockyleg. What do you want to do after you graduate?
rockyleg: I don't quite know yet, but I do know that I don't want to go into Cosmology or something in that area.
ZapperZ: Well then, do you have any other area of study that you are either good at, or interested in?
rockyleg: I'm not sure. That's why I'm here to ask you.
ZapperZ: Well, what about your grades at this moment? Are you doing well or are you struggling?
rockyleg: I'm [insert current performance here].
ZapperZ: OK then, do you think you are capable of handling an upper level or graduate level classes, or do you think you should be taking another advanced undergraduate course, just to make sure you don't go over your head too much? After all, you are not sure yet where you will be going. Taking another advanced class such as GR might not only be not as relevant to your future goals, but it may be unnecessarily difficult that it might affect your grades.
This is why I keep asking you, and other members who come into this forum asking the type of question, on whether you have had a sit-down conversation with someone who will have and should have a lot more information on not just about you and your academic state, but also the nature of the courses at that particular institution. These are not something a bunch of strangers on an internet forum will be privy to!
I've advised students on things like this, and I can tell you that their body language alone tells me a whole bunch of stuff that even they couldn't convey! I can sense hesitation and uncertainty despite the words the students tell me.
You have access to the best person/s who can help you find answer to such a question. Go talk to him/her/them!
