The account that I recommend for Janelle for saving towards her textbooks, which she buys every six months, is a Certificate of Deposit.
A certificate of deposit is a fixed deposit account offered by banks and other financial institutions.
The advantage of a certificate of deposit over an ordinary saving is that it has a fixed interest rate and the rate is premium, that is higher than the ordinary savings account's interest rate.
Thus, since Janelle does not require the amount until six months, it would be better for her to choose a certificate of deposit that will earn a higher interest.
