You have to appear for Online tests like Whizlabs before exam. Main exam contains mainly 2 types of questions, 1. Drag and Drop questions 2. Multiple Choice Questions 2.1 Involve Code blocks 2.2 Select [one/two] correct statements. So if you want to feel comfortable in Main exam, better to give some online tests.
All the best.
