Exam Tips
Development is hard to get your head around especially if you have no prior experience with it. I failed my first attempt at the developer I exam. Starting from scratch I would think it should take around three months of studying to pass the exam.
Always try to eliminate two answers that seem wrong so it becomes a 50/50 chance of getting it right.
Book your exam early so you are working towards a goal.
Sleep well
