There are many providers that are providing tuition for the ICB qualifications. Are you looking for a structured course with assignment work and tutorial support, or a self study course option.
We at Ideal Schools provide a tutorial service along with a course of study written specifically to prepare students for their end examonation with ICB. If you'd like to talk with an advisor you can call us on 0141 248 5200, or you can visit our website via the ICB College page, where you'll see a list of all providers: http://www.bookkeepers.org.uk/Where%20To%20Study
If you just want a textbook to self study then there is one in the ICB online store here http://www.bookkeepers.org.uk/Shop/Product/Practical_Bookkeeping_(M1_M2)
But as Brian said above, there are other providers who also offer tutor support if you should need it. It's up to you to decide how you want to study and how much support you think you will need though.
