I am confused which variant to choose and I am doing self study i am confused which one to choose what are its pro or cons. Do we have a separate textbooks for both ?please guide me.
Yes, there are separate syllabi and textbooks for different variants. I have no idea about other variants as i have done UK variant, which is quite easier.
Here on Opentuition, there are lectures for UK variant only. If you choose to go for it, you’d find them quite helpful and probably wouldn’t need any textbook. These lectures along with lecture notes are more than enough to pass the exam. However, you’d need a revision kit from an approved publisher like BPP or Kaplan for practice.
