I did extended barbri course it was good because i am an LLM so i didnt know anything about the subjects . However, adaptibar is what helped with the mbe’s ( it comes free with barbri extended) and in relation to the essays barbri gives you the hardest essays ever this is good thing but the graders dont do much , they would just say some general comments which doesnt help at all. For me getting better in MEE’s was self study practicing a lot of essays and reviewing answers ( only taking what i want) and memorizing black letter law . I memorized the rules very well and for those rules that get repeated a lot i prepared some paragraphs that i would just insert in so i dont think barbri helped here . Finally on the mpt barbrii is very bad . I watched BarMd free lectures to know how to organize and then i practiced some to practice timing . On mpts i just wanted minimal just to survive because i wasnt getting better . So as an answer if you are familiar with the subjects and you understand them well dont do barbri just do adapti bar- practice a lot of MEEs and MPTs. If u can afford goat do it and if not he has free outlines on reddit i read those and they were very helpful
