ATECH ACADEMY believe that "Teachers are an essential part for enriching the environment in classroom that supports in student success."
Best Coaching Classes are given to 12th Students for CHEMISTRY. We have Expert and Experienced faculties having more than 25 years of Experience. Students from VIP Road , Zirakpur, Mohali, Chandigarhand Panchkula are already taking the advantage and returning the productivity of our efforts and hard work in the form of Excellent Results.
We assist our students to perform better and achieve desired results in their exams. Our faculty applies the self –learning and assessment tools for the growth of students, along with this we work on the student’s over all personality grooming by giving PD sessions time to time. We ensure one to one attention to be given to our each student, to boost up their performance. We apply the following tools in Quality and well programmed classroom coaching to meet the targets of Teacher, Students and Parents.
1. Personalized Learning: Our faculties are highly experienced hence they enables and enhance a student’s learning skills which includes the use of expertise and statistics to resolve complex issues, running collaboratively, communicating efficiently, mastering how to analyze, and growing instructional mindsets. They empower students to be actively involved in the processes of their own learning, rather than passively receptive.
2. Weekly Mock tests: We conduct tests on weekly basis, to have strong command on the covered topics and to clear the doubts related to subject if any. This helps in developing self confidence and performance in the exams.
3. Timely completion of syllabus: We ensure to complete the syllabus timely so that student have enough time left for the revision and doubts clearing sessions can be conducted before final examinations.
4. Educational videos: The videos are made for important topics and same has been uploaded for the convenience of students which helps them to revise those topics being taught in class.
5. Free Educational App: Online educational app is available for our foundation group of students covering all the important area of their syllabus. Students can take help to make handy notes from the app and can use them for further competitive exams.
6. Get Online Assignments: We provide multiple assignments covering each topic which is helpful in examinations and class room tests.
For students to learn, they must feel safe, engaged, connected, and supported in their classrooms. It enables them to succeed further in their respective careers and life.
