SBL Exam Syllabus and Another exam

Dear all,
I am a Indian CA and planned to start my ACCA. I am in mid Sep 2020 and thinking of appearing for 2 exams in Dec 2020. One exam i had on mind was SBL, Can anyone suggest me with Other exam i should think to give in Dec.

Another thing i had in mind, I read SBL notes of Open tuition, just one glance and I could find similar syllabus as to Business Studies of Class 12, a bit of IT from CA IPCC and Costing from CA Final- Standard, marginal and other types of costing.

Can anyone provide me confidence on same if i am thinking on the correct path? Also, let me know if it is more of theory exam and can explain case study how it is provided in question?

Thanks.
