Kaplan study text and exam kit. I have so far passed all my papers first time including the dreaded Performance Management. The secret lies in question practise. Make sure to solve all the questions and knowledge checks in the study text and exam kit. Then review the model answers and notice where you went wrong. More importantly, understand why the given answer is correct. And finally, practice using the online software. I self study and I work full-time in non accounting sector. So it’s possible. Just perseverance. Best wishes next time
