Hello aspirant , hope you are doing well. Yes, it is totally possible for you get that this much marks in an annual if you do enough hardwork and clear all the basics.

Obviously , you'll have to devote a lot of time as it is not very easy but you can surely do this.

You can start by perfecting the chapters having more weightage in the exam and than slowly you can progress with other chapters as well.Also can you please specify for which field you are preparing ? .I might share some information that'll help you.

Thank you
