Need Your Advice

I had prepared well for my F1 exam and I had gotten 40 %. I had understood and learn all the chapters and had gone through the videos and practice questions. I had bought last year paper and did practice. I had got 80 % in last year exam paper. Even with revision kit half I did.. I felt so bad when I knew I culdn’t pass… Am confused now From where should I start studying again?? In the exam I was not able to understand some technical terms like pharming and phishing… From where can I learn about such terms ??

I will be waiting for your reply…

THANK YOU in advance
