Saloni Singh 23rd Dec, 2019

Hello Peince,

Hope your preparation are going well.

Well, for any exam, you should practice the previous year papers first and then the Model Test Papers. Question Paper are likely to follow the same trend as they've been following from previous years. So, projecting those trends and getting well prepared with that will be more productive than the Model Test Papers. But for the safe side, please solve both the papers before exams.

All the best for your exam Peince.

Hope I helped.
