See most of the colleges usually don't take entrances for MLT course. Also there are no such examination national or state level which takes a exam only for MLT or such courses. So if a entrance is required then its entirely by the college which you are taking admission in. Thus the college you want to get in, you must be aware if there is any entrance. If you see that there is no entrance then it will be on your merit and if you think there is a entrance then you have to attempt for it.
