I have now completed both AAT Level 2 and Level 3 Bookkeeping with McArthur Online and am still very happy with their tutelage.
I enjoy working through these courses at my own pace and the videos and other materials provided allow me to do just that. The tutor in the videos will usually give examples or explain complicated things in a simpler way to try and help with understanding. And is also easily contacted if you require more clarification on anything.
I passed my Level 3 Bookkeeping with a Distinction and will most certainly continue using McArthur Online when I study further with Level 3 Accounting.
