NetSuite SuiteFoundation Exam
I’d recommend reviewing the Study Guide (found here https://www.netsuite.co.uk/portal/uk/services/training/suite-training/certification.shtml) in detail and, as long as you have access to NetSuite, SuiteAnswers should help to fill in any gaps in your knowledge.
Then the sample test should help ensure that you’ve covered everything.
I would also recommend taking the practice test. The practice test they have posted is very similar to the actual exam. When you are done with the practice test, create a list of all the terms you didn’t know, and questions you missed. Those are your study items in SuiteAnswers. No problem. Good luck!
