Dear Students/Parents We at 'Apex Institute' are committed to provide our students best quality education with ethics. Moving in this direction, we have decided that unlike other expensive and 5star facility type institutes who are huge investors and advertisers, we shall not invest huge amount of money in advertisements. It shall rather be invested on the betterment, enhancement of quality and resources at our center. We are just looking forward to have 'word-of-mouth' publicity instead. Because, there is only a satisfied student and his/her parents can judge an institute's quality and it's faculty members coaching. Those coaching institutes, who are investing highly on advertisements, are actually, wasting their money on it, in a sense. Rather, the money should be invested on highly experienced faculty members and on teaching gears. We all at 'Apex' are taking this initiative to improve the quality of education along-with each student's development and growth. Committed to excellence... With best wishes. S . Iqbal ( Motivator & Mentor)

Special Individual A en on :One on one classes or doubt classes apart from
the regular classes give individual a en on to each student. The doubt clearing
sessions which will give the student the right push to their goal.
Faculty :This is one of the most important considera ons while deciding about a
coaching centre. We believe good teachers have the ability to transform students
en rely from non‐thinkers to intense‐thinkers.It is your responsibility to find out
whether the Ins tute does have Strong Pool of Full me Faculty Members or not.
This is important in case a Faculty leaves the Ins tute midway so that Ins tute is
capable of filling that vacancy with a Faculty of same Calibre & Exper se, eventually
safeguarding your future.
Result :So many coaching ins tutes show their results but don’t tell about the
selec on ra o, how many students were enrolled for a course, like, say IIT‐JEE
or AIPMT, how many were successful, what percentage of students secured ranked.
Student Teacher Ra o : Number of students per class is also a factor, the less
number of students for class the more is the a en on by the teacher on the
students and also by the students towards teaching. So check out for number of
students the ins tute divides for a single class.

APEX follows a very Strong, Systema c & Objec ve Selec on Process. Apex
conduct demo classes and mock sessions for students to help in making
correct and wise decisions.
At APEX the Student‐Teacher Ra o is less than 25:1,even at the peak me.
This facilitates proper Student‐Faculty interac on. Our faculty is always
willing to clear doubts of Students even individually, if required.
Apex consider doubts as the stepping stones towards understanding. each
me a modules gets completed its is followed by a doubt class. A doubt class
on any topic can be demanded by the student, throughout the year round.
Tes ng & Feedback system The only parameter to judge one's posi on in the race
is by analyzing the performance in tests. If students are to benefit from feedback,it
must not only be mely and frequent, but also useful for improving performance by
addressing three areas: what students did well, what students need to improve on,
and how to make this improvement.
At Apex, aspirants are exposed through weekly test and all India test series.
The weekly tests ensure that aspirants keep their pace with content coverage
and keep iden fying their week areas. Regular tests are conducted and results
