There is something that has been bothering me for some time and that I just haven't been able to figure out. And that is whether it can be grammatically correct to only use "am" as opposed to "I am" or "I'm" if an "I" precedes the pharse earlier in the sentence.

Example: "I catch on quite quickly and am not dumb either". as opposed to "I catch on quite quickly and I'm not dumb either".


Thanks,

Timo
