Guidelines for 12th electronics latecomer students

This article of “Best tips and guidelines for latecomer students of 12th standard” is for the students who think that…

  1. I have not yet studied anything about 12th bifocal electronics (C2) subject.
  2. I don’t know what books should be referred to start the study of 12th electronics subject.
  3. I was busy in the preparation of PCM study and forgot about this subject at all…!
  4. My PCM teachers told me (or in other words, misguided me) that this subject is easy and you can do its study later on…!
  5. I studied PCM with JEE Main and other competitive exam preparation at KOTA or other such institutions, so couldn’t have enough time to think about this subject.
  6. I’m from such city or village where I didn’t get any education or guidance for this subject.
  7. I thought that I will get 100 marks in practical examination from my college, so there is no need to study this subject hard (this is perhaps the biggest mistake you did or you’ll do in your life).

If you think that you fit to any of the points given above then its a very serious matter.

If you are reading this page during January to March, then it’s extremely serious.

But don’t get panic…!

You can still do quite well! 

Now very seriously follow my guidelines, and read very very carefully….! Understand each and every point given below…

Now if you very late to start the study of this subject, then you must concentrate on only following chapters from paper-1 and paper-2:

11th std. bifocal electronics book

Keep this book with you while watching these video lectures

If you have already purchase my notes, then I suggest you to watch my following video lectures first to build your concepts in basic electronics.

  1. Fundamentals of electricity
  2. 11th Bifocal Electronics Fundamental Concepts
  3. 11th Bifocal Electronics Video Lectures: Chapter 1
  4. 11th Bifocal Electronics Video Lectures: Chapter 2
  5. 11th Bifocal Electronics Video Lectures: Chapter 3

Paper-1, Applied Electronics

  1. Instruments – 15% – this chapter is very important, watch my complete video lecture
  2. DC Power Supplies – 20% – this chapter will be helpful for understanding concepts in Chapter-4
  3. Operational Amplifiers – 25% – extremely important chapter. Watch my video lecture to start!

Paper-2, Digital Electronics

  1. Number systems – 15%
  2. Logic Gates – 15% – Watch my video lecture on Binary AdderDe Morgan’s Theorem and Full Adder
  3. Combinational Logic Circuits – 20% – Watch my video lecture on Mux, Demux, Decoder
  4. Flip Flops – 20% – Watch my video lecture on RS Flip-Flops

With complete study of these chapters, you can score more than 70% marks in the HSC board examination coming in March this year!

How to study of the chapters?

  • First order my complete notes (you will get exam season discount now) of this subject, which are very popular all over in Maharashtra since last 26 years.
The complete note of 12th electronics

The complete set of my notes for your perfect study

  • Or you can use any other books of this subject like Nirali Prakashan books. But remember, these books contain lots of errors.
  • Well, whatever is your decision, proceed to the next step.
  • Now just go through the contents chapter by chapter and understand the flow of topics in my notes.
  • After that go to this link and download all the Chapter-wise Open Book Test Papers designed by me. Solve all those papers keeping my notes OPEN infront of you while solving these papers.
  • Believe me! When you will start solving these open book tests, you will automatically search for different topics, in each chapter. This will make you understand the structure of complete syllabus of this subject.
  • Once you solve all these tests, you can send me the photo copies (take photos using your smart phone) of the answer sheets on my Whatsapp profile. I will check them and will send you marked copies with any corrections – this facility is available for those students who purchase my notes.
  • You can also download the complete syllabus of 12th electronics if you have any doubts regarding the scope & limitations of the subject.
  • Ok. Until now we discussed about the preparation of theory part of the subject. Now if your college is serious about doing practical experiments also, then read the next important points about practical part of 12th electronics.

How to prepare practicals?

The practicals experiments of 12th electronics are very interesting. Those who never studied these experiments will surely loose the practical and applied approach of this subject.

The practical examination of 12th electronics conducted by HSC Board. You have to perform two experiments – one each from paper-1 and paper-2 sets of experiments, as given below.

  • Practical experiment Paper-1: 25 marks – duration 03 hours
  • Practical experiment Paper-2: 25 marks – duration 03 hours
  • After performing the experiment in annual practical examination, the student has to face oral examination, which will be conducted by external examiner.
  • Oral exam on experiment of paper-1: 05 marks
  • Oral exam on experiment of paper-2: 05 marks

As per the HSC Board rules and regulations, each student has to construct one project (from any one topic of the syllabus) for which 40 marks are allotted by the internal examiner of the subject. Thus, the total marks distribution is as follows:

  • Theory: 50 + 50 = 100 marks
  • Practical: 25 + 05 + 25 + 05 + 40 = 100 marks

Note: If you have not submitted your project report, you can download the FREE editable MS Word copies of 12th electronics project reports.

And finally…

I have been publishing guessing papers, since last 10 years for HSC Board examination of 12th electronics. You can download the guessing paper(s). You can also download some important study material from these links.

Important Note: All these downloads are free. Only you have to click on the blue button to share them on your Facebook Profile. After that the download will automatically and quickly start.
