Hi,

Yes, you can prepare and sit for both the exams. Go through the syllabus and solve and analyze previous years' question papers of both the exams as this will help you get familiar with the exam pattern and marking scheme. You'll also get to know the different types of questions asked in both the exams. Secondly, you must get all your queries/doubts cleared from your teachers or friends as this will go a long way in getting your concepts clear.
