HSC Board Paper Solutions: Perfect Answers

It is most helpful for the students of 12th bifocal (vocational) electronics. It contains the edited, logically thought and systematic solutions, according to Board pattern, for all questions asked in last 5 years HSC Board exam question papers.
Neatly drawn diagrams are also included. I suggest the students to remember and write the labels within the diagrams wherever applicable because the labels in the diagrams create good impression on the valuer and helps understanding of the topic that what exactly the student wants to express!

It is the BEST SELLER BOOK since last 5 years. We sell about 2000 copies, every year. The HSC Board Paper Solutions, PERFECT ANSWERS is only for Paper-1 i.e. for Applied Electronics. We do not provide such paper solutions for Paper-2 i.e. Digital Electronics. It is simple paper, so no need for paper solutions.

Other Useful Material

Solved/unsolved problems booklet - Paper-1
Practical booklet Paper-1
Practical Booklet Paper-2

The practical booklets covering important experiments with readings, circuit diagrams, procedure, observation tables, brief theory, specifications of components used, etc.

सायटेक स्टडी सर्कल
आज सायंकाळी ५ वाजता आपण मीटिंग घेणार होतो. मी बरीच वाट पहिली, विद्यार्थी बरेच आले होते, पण टीचर्स, पालक किंवा ज्यांनी माझ्या स्टडी सर्कल पोस्ट वर खूप उत्साही कंमेन्ट टाकल्या होत्या त्यापैकी कोणीच आले नाही.
आणि ते अपेक्षितच होते...!!
तर विद्यार्थी मित्रांनो, आता मी स्वतःच यामध्ये जास्त लक्ष घालून एक प्लॅन तयार करतो आणि आपण "सायटेक स्टडी सर्कल" सुरु करूया. (लक्षात ठेवा, well begun is half done!) अकोल्यातील काही प्रथितयश लोकांचे मार्गदर्शन मिळते का ते नंतर पाहू.
Okay? So, please wait and stay connected with me!
Remember: This study circle activity will be fully free...! Not a single penny will be charged or given to anybody, who might help in its development and smooth conduct...!
So those who are interested in this activity, are welcome to share their contact number, on this post. I will personally contact them...!
Thanks for reading this post...!

अकोल्यात एक "सायटेक स्टडी सर्कल" बनवावे असे वाटते. विद्यार्थ्यांनी व नवीन शिक्षकांनी पुढाकार घ्यावा. सभासदत्व पूर्णतः मोफत ठेवावे. महिन्यातून एकदा (१-२ तासांची) सायन्स व टेक्नॉलॉजी वर विस्तृत चर्चा व्हावी. प्रत्येकाला आपले विचार (नुसते लोकांसमोर उभे राहून, किंवा ब्लॅकबोर्डवर किंवा प्रात्यक्षिकासहित) व्यक्त करावयाची इच्छा असते पण असा प्लॅटफॉर्म मिळत नाही. तसेच या निमित्ताने अकोल्यातील प्रतिथयश व्यक्तींचे मार्गदर्शन आपल्याला घेता येईल आणि सर्वात महत्वाचे म्हणजे भावी पिढी घडवण्यास मदत होईल...!

आयडिया कशी वाटते?
