Do we need to do all illustrative examples from the standards issued. Practically, it doesn’t seem possible. Are OT notes sufficient for SBR, or do we need to consult standards as well?
I don’t think that will be necessary. The free lectures along with lecture notes do contain the necessary knowledge needed to pass SBR. Practising those illustrated examples can act as an additional understanding tool though.
Remember, you must practice as much as possible past exams. Practice is vital to pass SBR exam.
