Hi, your question is kind off incomplete as it is not giving me enough information of what you really want help with. Considering that you want to take admission in science for your higher studies. You will have to score good in your 10th standard exam and will have to take up the admission in science. While taking science as a career option you can choose from three options that is PCM, PCB, PCMB. PCM is for engineering students. PCB is for medical students. PCMB is for students who are not sure about their career path.

Now, if you asked for how to complete these two years properly I would recommend you to take part in extra curricular activities and look forward to know what you really like and don't. Also, look up for all the entrance exams you will have to give and start preparing. If you are still confused you can comment back here itself. Thank you.
