CertIFR Certificate In International Financial Reporting Standerds

Dear Sir

I hope you get my message and everything are going well.
Actually I need your help, I tried to pass CertIFR 3 times but in the first and second trial I got 48% and the last attempt was 40%.

I purchased the course of ACCA by GBP 130 but it seems I lost this money as the course was very short and every time refer me to Deloitte IASPLUS website.

Please help me how to study well this course and how to pass , my work experience more than 8 years approx.

Thanks in advance and so sorry to disturb you.
