FIITJEE Faridabad Vs VMC (Founder/ Extremex) How to decide

3:52 AM

FIITJEE Faridabad or VMC (Extended / Regular (Now Founder/ Extremex) How to Decide?

Are you staying at Faridabad and in a dilemma about making the right choice regarding selection of a coaching program? Read on..... 
(Disclaimer: You may always accuse me of being partial since I AM an employee of FIITJEE Limited (And proudly so for being associated with a team of bright and enthusiastic faculty members and students))

Here are some questions/ facts to be considered:

1. VMC was once a great brand where the three brothers themselves used to teach , however last year they have sold out to Educomp. So is VMC now still the same VMC or  has gone in to commercialization and encashing the brand image? It opened 22 centers simultaneously. Will it be realistically possible for the brothers to take classes at all these centers?

2. It is told that the same brothers (one of the three is now permanently settled in US) will also be holding classes at Faridabad. Will it be through video conferencing? Can class control be achieved through video conferencing? Ideally the student teacher ratio should not exceed 50 if there is to be a proper communication. (What about class control, so many times teachers repeat the ideas looking at the body language of the students, is it even possible through video conferencing?).

3. FIITJEE Faridabad has produced excellent results in the very first year of its operations. In a small lot that the center had for the first year, It has 4 selections in RMO/GMO (Practically half the results from Faridabad). (It is Worth mentioning that in GMO only two students had qualified from faridabad and both students are from FIITJEE Faridabad besides there was also another student in RMO who was from FIITJEE Kalu Sarai).

4. In NTSE Out of total 24 students selected in the final stage, 5 students are regular classroom students of FIITJEE Faridabad. Besides Out of special NTSE support sessions that FIITJEE had arranged, 13 students cleared the final stage. This means 13 out of 24 students selected in final stage of NTSE were associated with FIITJEE Faridabad.

5. In NSEJS (First stage of Junior Science Olympiad), out of a total of 6 students selected from entire Haryana, 3 are fiitjee students (2 regular students and 1 from special NSEJS support sessions).

6. It is a general experience of students that FIITJEE Faridabad teachers are very caring and cooperative. So many students take so much extra contact time from Faculty for clearing of their doubts and faculty are always ready in their service. Is it even possible for a Student going to Punjabi Bagh on weekends to Clarify his doubts in the weekdays. Can one run all the way from Faridabad to Punjabi Bagh?

7. A few years back in the regular classroom program out of 15000 students (who appeared in their test), VMC has selected about 200 students. That means that statistically , this test was significantly more tough (or competitive) as compared to IIT JEE (8900 selections out of 4.7 lac). So, out of these, students, the expected selection rate in IIT JEE must be 100% ....  Was it really 100%? ... No. it was about 60% (Yes! You read it right! From regular, not ECC.) (That too when they would move some of the relatively low scoring students  from the regular batch to correspondence (thus reducing the denominator)).

So What should I do?
   Of course,  as a career conscious student (or parent of a student) you should doubt everything that I (or for that matter anybody else) might say and do an independent research. Ask the already studying students (who are taking coaching) and their parents : if they are satisfied... If they really feel cared for... If their doubts are addressed.... It's a matter of your career so please do make an informed decision.
                                                  God Bless! 
                                                                                   Wishing you all the best,
                                                                                    -Ambarish Srivastava

Extra Topics in Olympiad Syllabus (As compared to IIT JEE Syllabus)

11:26 AM
The syllabus below is copied from HBCSE website and additional topics are highlighted red. If there are any comments I have used a green font for them. 

General :
A.The extensive use of the calculus (differentiation and integration) and the use of complex numbers or solving differential equations should not be required to solve the theoretical and practical problems.

B.Questions may contain concepts and phenomena not contained in the Syllabus but sufficient information must be given in the questions so that candidates without previous knowledge of these topics would not be at a disadvantage.

C.Sophisticated practical equipment likely to be unfamiliar to the candidates should not dominate a problem. If such devices are used then careful instructions must be given to the candidates.

D.The original texts of the problems have to be set in the SI units.

c] Energy levels of nuclei (qualitatively), alpha-, beta- and gamma-decays, absorption of radiation, halflife and exponential decay, components of nuclei, mass defect, nuclear reactions.

B. PRACTICAL PART
The Theoretical Part of the Syllabus provides the basis for all the experimental problems. The experimental problems given in the experimental contest should contain measurements.

Additional requirements:
1] Candidates must be aware that instruments affect measurements.

2] Knowledge of the most common experimental techniques for measuring physical quantities mentioned in Part A.

3] Knowledge of commonly used simple laboratory instruments and devices such as calipers, thermometers, simple volt-, ohm- and ammeters, potentiometers, diodes, transistors, simple optical devices and so on.

4] Ability to use, with the help of proper instruction, some sophisticated instruments and devices such as double-beam oscilloscope, counter, ratemeter, signal and function generators, analog-to-digital converter connected to a computer, amplifier, integrator, differentiator, power supply, universal (analog and digital) volt-, ohm- and ammeters.

5] Proper identification of error sources and estimation of their influence on the final result(s).

6]Absolute and relative errors, accuracy of measuring instruments, error of a single measurement, error of a series of measurements, error of a quantity given as a function of measured quantities.

7] Transformation of a dependence to the linear form by appropriate choice of variables and fitting a straight line to experimental points.

8] Proper use of the graph paper with different scales (for example polar and logarithmic papers).

9] Correct rounding off and expressing the final result(s) and error(s) with correct number of significant digits.

10] Standard knowledge of safety in laboratory work. (Nevertheless, if the experimental set-up contains any safety hazards the appropriate warnings should be included into the text of the problem.)


Please note:
  • The syllabus for  National Standard Examination in Physics (NSEP) is broadly  equivalent to the senior secondary level (Class XI and Class XII) of CBSE Physics. This is only a rough guideline, and there is no detailed syllabus given for NSEP.
  • The syllabus for Indian National Physics Olympiad (INPhO) is broadly similar to NSEP but the difficulty level of the questions will be higher. Questions and problems in National Olympiads are usually non-conventional and of high difficulty level, comparable to International Olympiads.
