why does the opentuition note say that these notes are not meant to replace the study text? is it necessary to get the study text or could i pass my acca bt exam without the study text ?
The statement simply means that notes, by definition, will be less detailed than a study text.
However, many students successfully pass BT without using a study text (which can be overwhelming in its length and detail). They use our notes, lectures and, very importantly, they buy a revision kit from BPP or Kaplan so that they are provided with lots of question practice.
