Hello aspirant,

No there is absolutely no problem in doing Bachelor's in science and then applying for lecturer in universities.

The eligibility criteria for assistant professor is

• The candidates should possess the SET/SLET, NET certificate and have a Masters degree in the required field.
• A minimum of 55% marks is required at the post-graduation level.

In your case you have masters in political science hence you are eligible to become assistant professor for political science or related subjects.

I hope this information helps. Good luck.
