Passed 58% first sitting. i managed to stay calm during the exam when i could not answer 2 questions worth 16 marks and hear i am with a pass. praise be to God.
On learning curve, month one there was 1 batch, month two, 1 batch again, month three, 2 batches month four. 4 batches and month five 8 batches.
Using the learning curve fomula 1st month and 2 month of same output got the same cost of labour because output did not double. I went on further to calculate the difference in cost of labour for the 3rd nd 4th output which I used on the 5th month of 8 batches since learning was ending on the 4th month. Don’t know if I got it correct
