Hi guys
I was wondering if any of you could help. Today I failed the ICND1 test with a mark of 687. I probably would have got over the 700 but never realised on simulator questions once you move to next question you cant go back

Never the less I know I need to vastly improve in order to pass the exam.
The methods I used for studying was I purchased an online course Mindleader.com which I found helped a lot with the basics. I also purchased the exam simulator from boson.com which to be honest was a little disappointed in. The answers & explanations were really good but the test questions I found were really easy compared to the exam i.e. I repeatedly went through them & was getting over 900 points in each test exam so I was quite hopefuly going into the exam. What did surprise me from the questions were they were a lot different from questions in Boson simulator & included some things which I havent really covered from my study.
Im just wanting to get any feedback at all on what other methods of studying I can use in order to improve on my mark. Is there any other test simulator package on the market which would be better than Boson? Or alternatively is there any other methods of studying you can recommend I use?
Any help greatly appreciated.
