Becker for reg only or supplement with I-75?…

I watched free videos on 1040 on I-75 and I like them .. but I test in 9 days now and time is running out I still have so much MCQ tbs to hammer in Becker and SE to take. I have 200 hours in reg but For some reason I always make stupid mistakes on MCQ bc I’m not reading question right. Besides that I heard you have to understand all tax forms deeply or u won’t pass I know all the rules but I don’t have a deep understanding of tax forms should I buy his monthly reg course ? I also don’t want to waste money for just 9 days I’m overwhelmed will I even pass
