Teacher

Hi Manik,
Salary is a function of various factors - i.e. (i) the institute where you have completed your B.Tech + M.Tech. e.g. a graduate from a top institute will command a higher salary. (ii) Your work experience - organization and type of work profile (iii) city - a metropolitan city will have higher salaries as compared to smaller cities and towns. (iv) Your current organization - i.e. where you will be joining - an MNC usually has higher salaries as compared to other organizations. (v) Your work profile i.e. Manager/ AVP, etc. Thus one cannot allocate a figure.

Wish you luck.

Hi Manik,
1. If you wish to be a teacher in school, then go for B.ED and crack Teacher Eligibility Test. Eligibility conditions are:
(a) Bachelor's Degree with 50% marks in aggregate in the 10+2+3 or 11+2+2 pattern, or with a minimum of 55% marks in aggregate in the 10+2+2 or 11+3 pattern
(b) Having studied at least two subjects at the bachelor's degree level, to be later taken as school teaching subjects
2. Else if you aim at being a lecturer, then I would advice you to go for a regular masters degree in a relevant discipline and clear U.G.C NET conducted mainly to recruit research assistants and professors in various streams of education.
