You're not supposed to talk about content until it is released as a preptest. All I know is though, traditionally the experimental section is section 1 through 3. Plus, no one could answer this even if it was against the rules, mainly because the order of sections and people's experimental sections are different. You may have had an LR experimental section for a test and someone else could have an LG or RC experimental section in that same test. But again, remember, you're not allowed to talk about test content until the test is disclosed.
