Hello aspirant,
You can definitely pursue a BA(Hons.) Psychology from DU SOL after completing your BBA from GGSIPU.

There's no restriction on pursuing another bachelor's degree after completing one. Many people opt for further studies to enhance their knowledge and skills or to explore a different field of interest.

Eligibility criteria for DU SOL might vary, so it's essential to check the specific requirements for the BA(Hons.) Psychology program. Generally, you'll need to meet the minimum educational qualification and any other specified conditions.

I hope this information helps.
