Really?! I found that it would be more beneficial to change as sole trader, because I calculated the corporation tax + income tax liability + NI employee + NI employer. For the sole trader I calculated the income tax liability + Class 2 + Class 4. Did you also do this or you tried a different approach?
Passed with 55%! Really happy, especially if I consider that both times I studied with open tuition, I had only 2 weeks for each course (my first one was PM) and managed to pass both attempts just by reading the notes and listening the videos from Chris!
