Panic won't  help. Identify your study comfort and start. It's better late than never! Speaking of me, I generally prefer online solely for the reason that I like to study at my own terms and not on instructions! Online, you can learn from open sources! One of the best websites I feel, for people who want to self study is Studypal.co! You can take the help of Study guru from Studypal.co who will share with you his expertise and be able to guide you! You can even form study groups of people giving PMP in your vicnity. This allows you to monitor your growth. Hope this helps. :)
