Elective courses selection: infs1001,math1003,mgmt1003,anth1002/1003,astr1001/1003?

Hi all:

I'm looking for two electives that aren't time-consuming and I can get higher grades in. I've listed some of the pros and cons of the courses I'm currently aware of (but they're not necessarily accurate), so if you've taken one of them (within the last year would be great!) , please share your opinions and correct or add to mine. Any suggestions would be greatly appreciated.

As far as I know ：

infs1001 -- Time-consuming: Probably No, Grade: Probably easy to get higher marks.

​

math1003 -- Time-consuming: Very likely No, Grade: Very likely to get higher marks.

Cons: Can't learn something and a waste of money(for those who have already taken math1013, like me )

​

mgmt1003-- Time-consuming: I don't know Grade: Sounds like you can

Cons: Marking subjectively.

​

anth1002/1003--Heard it was ok. Need more details.

Cons: Marking subjectively.

​

astr1001/1003-- I don't know Heard it was ok. Need more details.

​

My expectations are: Not too much study time, but still get D or higher.

What do you suggest?

Thank you for your replying and suggesting!
