LWACCA F4 which variant to follow

Hello , My name is Tariq. I am studying for F4 and wanted to know which variant should i choose to study for my exam. The lecture page of F4 says that the lectures from chapter 5 onwards are relevant for bothe global and english variants. Now that i check the notes , the chapters in respective notes are different. This is kind of confusing me. Please let me know what notes to follow when going through the lectures. thanks in advance. Regards M.Tariq Shaheen
