So I am appearing for a certification exam soon and the exam is going to be conducted online via an aap. I initially planned to take the exam from home but it's impossible with the load shedding. My laptop battery will not last the 3.5 hours I need for the exams.

I'm looking for a place that offers reliable internet and electricity so I can take my exam in peace. I looked into the office spaces available at luckyone and such but they cost around 12-14k for four hours. I am not sure about any libraries or coffee wagera like places because I've never tried them before.

What other options do I have?
