<prompt> Human: Im 22, no previous debt and live in Canada. Recently got accepted to med school for which i took a 275k line of credit from scotiabank.Interest is prime currently 3.4537; - .25 and I was wondering if there was any smart way to invest 50-100k of it so that at the very least, it could cover the interest on the LOC and then some by the time i have to pay it back  <response>: There is no investment you can make with zero risk that will make more than the interest you are paying. Unless you can afford to lose that money dont borrow to invest.
