Step 1. Before taking a closer look at preparation resources, first take a look at the Written Exam Blueprint.

Step 2. Carefully consider how strong you are in relation to each of the objectives, then you may decide to approach the blueprint in a top-down fashion - just start with CallManager, and run through the objectives one-by-one. Or you may decide to fill in the gaps with subjects where are stronger before tackling those subjects where you are weaker. Or you may even decide to tackle the toughest subjects first, while enthusiasm is highest! Otherwise, take some substantial effort!

Step 3. It's probably best to set aside a certain amount of time every day to study for 350-030 exam, and stick to that schedule. You may find it useful to (briefly) record in a journal what exam preparation you do every day.

Step 4. Have a look at study resources that you can use in preparing for the exam. The resources include CallManager, QoS, Telephony Protocols, Unity, IOS IP telephony skills, IP IVR/IPCC Express, Security, Infrastructure protocols, Application Protocols, Operation and Network Management.

Step 5. So, you have stepped through all the study resources mentioned in step 4, and you are almost ready to book the exam. Find one resource that will help you to quickly fill in any gaps in your knowledge.

Step 6. At this point, you'll be ready to book your exam. It is worth mentioning time management for the exam. Don't forget that there are 100 questions to answer in 120 minutes. So, that's just a little over a minute per question. Don't get sucked into spending too much time on one question. If you have a problem with a question, mark it and go back to it at the end.
