Bluelines advice is good but i would like to add that you should not rush the IMC i found it far harder than the IR because it was all new to me the IR was just practice to get to a higher standard.
Not using this stupid QFE thing would have helped to avoid some mistakes and made the whole thing a lot safer.
I have found the Jepp aproach plates a lot better for single pilot flying as all the info is on one page with the aerad you have to find the limits on a green page, just what you want on a divertion ln bad WX.
I should add that the new aerad format is much improved but will take some time to impliment.
And finaly DONT put more than £100 cash up front.
Good luck and enjoy ,i did A and C
