Hello hello !!

As per your query , i am assuming that you are asking about how to take admission in btech college. See , if you want to do btech then first you have to clear your class 12th from science stream in which mathmatics is mandatory subject. After that some universities and colleges take direct admission on the basis of your class 12th percentage and some colleges have their own entrance exams. So , you have to pass those entrance exams to get admission in that college. And now the most famous entrance exam is JEE MAINS from which you will get the top most college and university in india. If you crack the exam then you will get IIT , IIITS , NITS. Jee mains means joint entrance exam conducted by the national test agency that is called NTA. This exam is a national level of exam. It conduct in fours phases in a year.
