IASbaba’s 60 Day Plan- Prelims Test 2017 Science and Technology and Current Affairs [Day 47]

Hello Friends

So, here we are with the 47th Day of 60 Days Plan. It is the third edition of 60 Days program but seems like the first one because of the excitement involved everywhere, including us 🙂

We are equally excited and pumped. Our Team is working hard to make you realize your dream. Do not take it insincerely and let us down. Your faith and participation has to be in sync with the amount of hard work and effort we do.

Let us pledge to make it a big game changer (better than last year) in the next 60 days!

Importance of Self – Tracking: Learning from Last Year

Last year, aspirants used to comment their answers in the comment box on daily basis. There were huge participation in discussion. Putting answers in comment box has been very effective to self track yourself after updating the score. In the end you can cross check your performance through disqus profile.

It was highly effective in the last edition of 60 Days that propelled aspirants to monitor their performance and learn through discussion. Let you solve these questions with full honesty and write your result in the comment box. Interact with peers to know your mistakes.

The importance of this initiative stands time bound and aggressive reverse engineering to learn the concepts. Many of you must be busy with your own strategy but let us tell you honestly that in the last two months, it is very important to revise and consolidate your learning. Just reading won’t suffice.

So, take out few hours from your schedule and make it a revision exercise.

How you can make the best use of it?

Be honest to your effort and do not start competing with XYZ aspirants here just for the sake of marks. It is more important for you to introspect and check your learning than focusing on others. Try to answer the questions in 20 minutes only. 

Do not get into negative feeling that I don’t have enough knowledge to answer these questions. Feel like you are taking the real exam. What would be your response then?

The same will be replicated in UPSC exam. Here, you get marks only and nothing else matters. So make effort to know the answers of all questions. Do not cheat 😛

Baba’s Gyan for REVISION

Many of you, almost all, asks about effective revision strategy! Can there be any?

Let us tell you something Baba does 😀 

You guys study a lot and there is no issue with the hard work that has been put in. But when it comes to input-output comparison, your performance is questionable.

What to do?

Just do this for a Week: Go to bed before stipulated time of your sleep, at least 1 hour before. Close your eyes and try to relax your mind. You should attain full comfort and calmness.

Do this on the First Day: Imagine the full story of a recent movie that you have watched. Try to recollect from starting to end. See, whether you are able to depict the clear picture or not!

Now, do the same for everything you learnt from morning specially the ones you struggled with. Since it is fresh, most of the things should flow into your mind smoothly. Check what is your recollecting capacity.

For example, if you prepared Polity Day 2: Topics- Try to collect all important concepts and learning of the day.

Trust us, this exercise if done with sincerity will give you immense confidence as well as boost your performance. There is no ideal time for revision and there cannot be any specific date put for it, as commonly done.

This will always expose your weaknesses the very same day and if you tend to forget something, can always get back to consolidate and cement it.

REPEAT IT FOR A WEEK & SEE THE MAGIC 😀 

Must to Do: Read the detailed article regarding Micro Analysis Matrix and follow the guidelines- Click Here

Try to hold your nerves and learn to control the temptation. This is very important art to learn and implement!

Are you ready? Let’s start
