Hello sowmya,
Yeah it is very easy and definitely possible to study physics of class12th just before two months ,you should follow these below mentioned tips
1. Check the syllabus of exam
2. Check the previous year question papers and make a mark  of the most repeated questions
3.set a timetable covering each each chapter in a specified time limit ,so that you can meet the all possibilities
4.best idea is go through youtube lectures videos daily ,because actions speak better than words ,putting some interest gives you a very informative knowledge which helps you to speed up your preparation
5.give preference to less important questions and thoroughly study the board exam papers ,it will cover all maximum topics
Good luck ,
Thank you
