Correct the mistakes
I have an exercise where I have to correct the mistakes in each sentence, but I can't find them in some of them and I'm not sure about the rest.
I'm going to copy here the sentences tthe way they appear and the part I think is the mistake will be between ()
1. I did (had) a really late night -I didn't get to bed until after four o'clock. (I can't find the mistake here)
2. When I first met Jake, he struck me like (good sentance, or you could use "as") a rather shalow person. (He struck me as a rather shallow person)
3. Then I got knowing him and my opinion changed. (I got to know...) use this one
4. My society life has been fantastic since I met Corinna. (My social life...) use this one
5. It's a problem, but I'm sure I can make something about it. (...I can do something...)
-I'm sure I can do something about it

-I'm sure I can make something of it
6. I can't work up the answer to this maths problem -can you help? (I can't find out...) use this one (without the "s" on math)
7. That colour really fits you -it goes with your eyes. (...-it matches your eyes) (both options are fine)
8. I'm not very interested in keeping on with the latest fashions -I just wear what I like. (...interested in following the ...)

o
-I'm not very interested in following the latest fashions.
9. The trouble with my flat is that there isn't much store space. (storage space) (good sentence)
