Can you take admision in 2nd year polytechnic?

No, you generally cannot get direct admission into the 2nd year of a polytechnic program. Polytechnic programs are structured sequentially, meaning you must complete the first year's coursework before progressing to the second. There might be very rare exceptions (like transfer credits from another institution), but these are not common and would require specific approval from the polytechnic college. You would need to apply for admission to the first year.
