F.E.M.ENTRANCE EXAM FOR CLASS 9
Often, it is confusing for a student to decide on a profession he/she would like to pursue as a career. Most of the times they either decide depending upon the marks they score in their Secondary exams or on the basis of discussions with parents, friends and other people whom they consider their guides. However, all these discussions may not always be conclusive. We realized this causes a lot of worry and discomfort for the parents as well as the students.
Keeping the above in mind SĀRĀ has decided to initiate a “Foundation for Engineering and Medical” (FEM) program. This program provides a course focusing on the Competitive exams that our students would be facing, once they decide to pick Engineering or Medical as their career option. We wish to groom and instill confidence in our students for these exams.
We would be inviting young professionals who have been ex-pupils of renowned Engineering & Medical Institutions to be a part of this Event as Guest Lecturers and to share their experiences and mentor our young brigade who aspire to become similar achievers and go-getters.
The FEM program would be covering Topics from the syllabus of IITJEE, AIEEE and AIPMT. The first phase for this program would be a 35 hours course extending over 4 months. Starting OCTOBER 4th , classes will be held every Sunday.
All those interested in participating in the FEM Program shall have to take an Aptitude Test (AT) on OCTOBER 2nd.(9.30 AM-11.00 AM) The participation to this program will be limited to students of SĀRĀ and their references (if any). On the basis of the results of the Aptitude Test, we would award a “Scholarship” to the top 25%. These Scholarship holders shall receive a waiver of 50% in their fees for the FEM program.
We at SĀRĀ share a vision of seeing each student soaring high in their careers and getting admissions into some great technical Institutions in our country and abroad. We look forward to hearing from you at the earliest to enable us to finalize our Program Structure.
Thanking You,

Happy Teachers Day (5/09/09)
Teacher's Appreciation Ideas
A teacher is someone who is the mentor of your life. Right from the nursery teacher who taught you to identify the alphabets to the one who was your project guide at your PhD. a teacher has been the guiding force of your life. He/She is the one who made you the expert of the subject you are and also, been the motivational factor behind your success. As a student, we often fail to identify the contribution of our teachers in your life but later in life, we realize his/her importance at every milestone of life. So, if getting a chance one must not forget to identify and appreciate the efforts which a teacher puts in giving a direction to your life. On the occasion of teachers’ day, commemorate the efforts of your teachers in various ways. We are listing below some of the teachers’ appreciation day ideas. Read these appreciation ideas for Teachers' Day and you will know how to appreciate your teachers.
How To Appreciate Your Teachers
Prepare Souvenirs
Print your teacher's names on coffee mugs, T-shirts, schoolbags, etc or to commemorate the efforts put in by your teachers.
Make Notes
Write teachers notes like "Well done", "Thank You"," You Are The Best", "You Are Appreciated", etc. Put them on the desk of your teacher before he/she comes to the class.
Activities after Tuition
Plan a party for teachers at the end of the Tuition Class . Organize some light games and provide refreshments.
Decorations
Decorate the staff room and the hallways of the school for Teacher's Appreciation Day.
Red Carpet
Create your own Walk of Fame for your teachers. Get a piece of red carpet or put red butcher paper down in the entry hall. Make gold stars with a teacher's name on each, and have the school meet the teachers as they arrive one morning.
Flower Shower
Make a student stand at the entry gate before the teacher's arrival. Shower the teachers with flowers when they enter the Tuition Premises
Say Thank You Differently
Prepare a group of twenty students. Write the phrase ‘THANKS FOR A GREAT YEAR!’ with each letter on a separate piece of paper. Now attach one letter on the front side of one student. Arrange the students in a horizontal line at the entry gate to form the complete phrase. Make sure all this is done before the teachers start coming.
E-mail
During computer class, send your teachers thank you notes via e-mail. When he comes up to you to say thanks, gift him with a wonderful flower bouquet.
Dress Up
On Teacher Appreciation Day, dress up as your favorite teacher. Ask him/her to take sometime off and take the class that he/she was supposed to take. But, don't forget to take prior permission from your principal for this.

Teacher's Day Celebrations(5/09/09)
All across the world, Teacher's Day celebrations are undertaken to honor teachers for their sincere efforts to impart knowledge to their students. By having celebrations on Teacher's Day, we convey the message that we care for our teachers, just as they do. Celebrating the festival is the recognition of the devotion, with which, teachers undertake the responsibility of educating a child academically as well as morally. On this day, school students dress up like their teachers and teach their juniors, the same way as their teachers do. As the day passes, the students perform the activities that are performed by the teachers.
Sometimes, the teachers also sit in the classes acting like students, reliving the time, when they themselves were students. This creates an understanding between the teachers and their students. Apart from being the day when we give recognition to our teacher's hard work, the festival brings out a healthy interaction between students and teachers, wherein the latter recognizes the teaching capability of the former. Even if it is simple celebrations, they reflect the fact that we care for our teachers.
All across the world, Teacher's Day celebrations are undertaken to honor teachers for their sincere efforts to impart knowledge to their students. By having celebrations on Teacher's Day, we convey the message that we care for our teachers, just as they do. Celebrating the festival is the recognition of the devotion, with which, teachers undertake the responsibility of educating a child academically as well as morally. On this day, school students dress up like their teachers and teach their juniors, the same way as their teachers do. As the day passes, the students perform the activities that are performed by the teachers.
