_*Benefits of Bifocal Electronics at Std XI ,XII.*_
* Increases Avg.%. Out of 200 Marks,100 for Practical.
* Exemption from 2 Subj. language-II & Biology or other Subject.
* Helpful for Std XII Physics, MH-CET, IIT, Degree & Dip Engg subjects.
* Eligible for B.E., B.Arch,B.Pharm,B.Sc (CS,IT)
* Direct admission to 2nd Yr of 3 yrs Diploma.
_____________-----________
*Advantages of Electronics over C.S at Std XI , XII level.*
* Electronics curriculum was almost same in past and will be same in future for many years.
>In CS there are continuously updates. What u learn today will be obsolete tomorrow or hardly be useful.
** Electronics subject
is more helpful than CS to score high marks in Physics, MH-CET, IIT Mains....
* Electronics is mainly hardware oriented. Also interesting. Hence you can construct your circuits, you can repair most of the electrical & electronics gadgets in your home with minor problems. Once expertize you can repair appliances with major faults.
> CS is mainly Software oriented.Hence it helps in developing softwares.
* Electronics students can also enter in to IT field.
