I bought the Tax critical file 3 weeks before my exam. I was screwed at that point but I was able to pass the module just based on the tax rec and tax bible resources alone. I wish I had more time to study now because the notes actually look really good.
The journal template in the FIN critical file saved my life. There was no way i could remember how to do all those journals myself, but the template showed me the framework and i just used this as a basis. The critical file & notes were also really well written, concise and cuts out the stuff you don't need to remember from the textbook.
