Hello.
No you cannot take direct entry in the second year if you are BSc student because this procedure is called lateral entry,  and there are almost not any university which provides you later entry if you have done your BSc and you want to take admission in 2nd year more specifically some University provide lateral entry for BSC (IT) in direct second semester if you have done any diploma with 10 + 2, moreover this thing is provided in the B tech /BE course.
Best of luck.
