Looking for trade advice

I’m finishing up university and I’m applying closer to the time I graduate, but I’m still stuck between going NCM or Officer for reg force.

There are quite a few trades that interest me, and I’m having a hard time narrowing them down. I spoke with a recruiter but basically just got a paraphrased version of the CAF website descriptions.

For those currently serving, what trade are you in, and would you choose it again if you could go back? What do you like or dislike about it?

I’m also curious about how much math is actually used in different trades. Math isn’t my strongest subject, so I’d appreciate any insight on that as well.

Thank you in advance!
