Hey If you’ve scored 158 cutoff marks , the colleges you can get into will really depend on which entrance exam or counseling process you’re applying through  like TNEA , KCET , JEE Main , etc. Your category (General, OBC, SC, etc.) and home state also play a big role.

if you're talking about something like TNEA (Tamil Nadu Engineering Admissions), a 158 cutoff might get you into

Some government colleges in less competitive branches

A good number of private/self-financing colleges across Tamil Nadu

For example, you might get options like

University College of Engineering, Dindigul

Government College of Engineering, Bodinayakanur

Private colleges like Karpagam, R.M.K., or Sri Sairam (but likely in IT, EEE, or similar branches rather than core ones like CSE or ECE)
