CFA level 1 hard question, help please

You have the following information:

. zero-coupon bond with 6 months to maturity, stands at 99

. 2% coupon bond with 1 year to maturity, stands at 101.5

. zero-coupon bond with 1.5 years to maturity, stands at 97

Compute the 6 months forward rate 1 year from today (ie 0.5f1)

a.2.63

b.2.74

c.3.20

help me please

For the 1.5 year zero coupon, you can invest at the 1 year spot rate and reinvest a the 6 month forward rate 1 year from now. You can solve for the 0.5 year spot rate from the first line and then use that to solve for the 1 year spot rate in the second line.

I get 5.1853%.

Are you sure that your numbers are correct? The price on the 1-year bond seems high.
