Completion of Group2 Classes for Jan'25

Hey Guys..I Cleared my Group1 Exams in May 24 and now I have my Inter Group2 Exams in Jan 25. Due to some reasons, I didn't buy and start classes for that. Yesterday I purchased Costing and Fm from Nitin Guru Sir and within one week I'll by buying Audit lectures from Neeraj Arora Sir. Actually the main thing is that I'm in a Regular College at DU. So, I seek advice regarding completion of Classes. How should I complete my classes within time and what should be the deadline? How many Lectures should I watch in a day? Actually I was thinking of watching 2 Lectures a day for costing. No idea about Audit and fm. For SM, I was thinking to start when I'm done with my FM Portion. Also, I feel that buying SM classes won't be worth it and can be done by self. I have no idea regarding this, one of my friend told me about this. Also, now festive months are coming so that would be a lot of distraction too. I want that atleast I should be left with 1 month for revision. In May 24, I completed my lectures almost 10 days before exams and only I know what I went through. By God's grace I passed. But I'm unsure of this one.
