Answer to your first question about being slow in calculation is not of much worry. You can overcome this problem only with stringent practise. Practise makes one perfect as well as fast in whatever he or she does. Secondly getting deviated from the situation, i think is an excuse. I believe there are two catagories in which all humans fall either hardworking or lazy to work. if and but are never ending terms, you have to overcome it and just stop thinking about all this. Decide your goal and without one blink just run behind it. Rest everything will fall in its place.

For improving calculation speed do not use calculators at all. Solve the question upto the very last step till you get the answer.
Secondly understanding a topic is of no use until you practice well. Selection in JEE requires a lot of perseverance. Many brilliant students fail to perform due to overconfidence.
Getting off distractions depends entirely upon you.You are grown enough and know your priorities. Please do not waste this precious time. This is the time you really make your life.
One important thing ultimately result matters. There are so many worthy candidates but a candidate is of real worth only when one clears the exam. So please keep away cell phones and other gadgets and focus well on your studies.
