Hello Gireeshma
It would be difficult to predict your marks as it depends completely on your preparation level and hardwork. Clearing of concepts is essential to score well in the exam. If you have complete understanding of the topics then you will be able to solve the questions without much difficulty. After completing any topic or chapter, you should solve questions related to that topic/chapter and I would also suggest you to solve previous year question papers, sample papers and mock tests. It will help you to know about the exam pattern and type of questions asked in the exam, difficulty level of the exam and also in time management. Time Management and Accuracy are the key factors to get a good result.
