Yes everything is possible if we are committed to it. Rather than quantity, its about quality. So take your each day as challenge, and keep struggling and learning more and more as you can every single day so that your concepts keep bettering with each passing day. Read NCERT as much as possible and keep solving more and more MCQs as much as you can so you expose to most of its types. At the same time, solve previous year question papers too, so that you can know the pattern and type of questions asked as well.
