CH is 120°. Deviation is +4°. Variation is 5° W. Wind correction angle is 8° Right. TT is: (choose below)

111°

127°

113°

129°

120-4-5-8=103 (T) ???

CH is 224°. Deviation is -3°. Variation is 4° W. TH is:

217°

223°

225°

231°

224+3-4 = 223(T) = answer b

CH is 317°. Deviation is +3°. Variation is 5° W. Wind correction angle is 10° right. TT is:

309°

305°

329°

325°

317-3-5-10 = 299 (T) ???

CH is 098°. Deviation is +2°. Variation is -8° and drift is 5° Left. TT is:

087°

093°

097°

109°

098-2+8+5 = 109 (T) = answer d

have I gone wrong somewhere on questions 1 and 3 ???
