IASbaba’s 60 Day Plan- Prelims Test 2018 SCIENCE and TECHNOLOGY & CURRENT AFFAIRS [Day 27]

Archives

Hello Friends, 

Welcome to Day-27.

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 can you 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 to all questions. Do not cheat 😛

DETAILED MICRO ANALYSIS MATRIX SAMPLE– is given here. You can download this and do an assessment for yourself.  DOWNLOAD

• You can copy paste the same format/modify as per your need in Google Spreadsheet and update it on daily basis.
• Feedback talks about daily test results.
• Follow-up talks about daily target achieved from sources and the number of revisions to do/done and dates. Sources column is to ensure that aspirants do not run behind various sources and follow the same throughout.

Are you ready? Let’s start!
