Readings of chemistry Practicals for Grade 12 students.

These are the images of the sample readings. Please do not copy them, just understand the method of calculation and the way of the writing the observations in your practical note book.
Taking the readings for the first time can be challenging and confusing so these samples can help you in understanding how these are to be attempted. Hopefully you do not have to search for Practical Copies of your seniors, brothers or sisters any more. Just be sure to take your own readings according to these sample readings.

What should your routine be before the Entry Test.

Since the Entry Test is around the corner. It is I guess on July the fifteenth, so here is a general idea about how your routine should be while attending the coaching academy as well as having to study full time:
  • So you should wake up early in the morning and say your prayers Because this time is so crucial, you need Allah by your side at all times.
  • After prayers go to a lawn/garden/park; any where green and revise yesterdays lecture which was taught to you at academy.
  • I would insist that you sit some where quiet and peace full and cool, considering you would have to bear the summer's heat.
  • Then have your break fast and go to the academy.
  • Once at the academy, make sure you understand every single thing the teacher says, note it down. Don't waste a single second there. This is the morning time, your mind is fresh and ready to absorb stuff. So don't waste this time.
  •  When you come home, have some food and some hang out time with your family. And the take a nap. I know the after noon is super hot and you would be tired from the day at the academy,so do take some rest.
  • Wake up at about 5. Get refreshed and sit down to study. If you cant do consecutive hours, take 5 minutes break after each hour but give at least 5 hours to your study. Take prayer breaks and dinner break but not long breaks.
  • At about 12 you should be in bed. Yes because "Early to bed, early to rise, makes a man healthy, wealthy and wise" is true.
  • Don't wake up later than 12 cause that things you learn will be temporary and will be forgotten soon.
  • Use your 5 hours study time in the evening very wisely.
P.S. If you are not attending the academy, this blog post is not for you.

How to deal with Organic Reactions.


How to learn the reactions of Organic Chemistry?
When one starts the Organic Chemistry in Second year, the first chapter that is the introduction is usually quiet easy to understand. The concepts are familiar to the one's we started reading about in the Organic Chemistry chapter from matric text book. How ever once the next chapters start, the concepts become too much to comprehend. Yes the physical properties, uses and structures are comprehensible but the chemical reactions are a bit too much.
With each successive chapter, the no of chemical reactions increases and it becomes confusing to remember what reacts with what to give you what. The alkanes, alkenes and alkynes all end up reacting with the same chemicals yet give varying products. here are some tips to make you understand the reactions in a better light:
  1. Keep a pencil and paper with you while studying reactions. The more you right things down, the more they stay with you for ever.
  2. Understand what is going on the reaction. This may seem tiresome but it is better to know where the electrons are going, how the bonds are being made and reformed again. So that if you forget the real equation, you can come up with it on your own using the chemical techniques which actually make the reaction happen. 
  3. This is also helpful in the Entry Test examination where the reactions may not be exactly like the ones given in the book. So if you know the mechanism of action, the organic chemistry multiple choice questions would be a piece of cake.
  4. Make it visual. the more you make the reactions elaborate and colorful, the better. This is specially good when you are beginning Organic Chemistry. Once you get a hang of this, you wont be needing too much illustrations.
  5. Also do lots and lots of practice on paper. The more you do that, the more it will stick in your brain. It is kind of like Mathematics in that way. Practice is the key.
