Ib math sl or hl

<p>Okay so I have been debating about this for a long time now, and I need an answer now. I am now a rising Junior and I still cant decide if I should take Math Sl or HL. I ended with a B in Algebra 2. My teacher played a big role in that B. I think I could have gotten an A though. Moving forward, I want to be an Aeronautical Engineer in the future and I would like to go to Virginia Tech. I know this is where people will be like HL, because you will need math in the future. But I dont want to ruin my GPA JUNIOR YEAR! I think V-Tech will only give you the credit if you score a 6/7.
So:
What do you guys think, should I take it? I mean math is okay for me. I heard you have to lovvvee math to like HL. I think math is OK.
1.) Is it really that hard?
2.) Will taking SL effect any chances of me getting in?</p>
