Trending @Infosys; Regarding BCEP Exam

How to complete bcep exam. I tried doing it through lex and once I complete the initial assessment in 4 topic it says you are placed level 7. Now do i need to complete the learning from level 1 to level 10 or only from level 7. Also do I need to complete the assignment also or only review test is fine. And if so what percentage we need to get in review test we need to score to be deemed as cleared.
