i love science subject but i cant understand it

HI,
First of all never stop doing something just because you are not able to understand it
Do more research,work a little harder you will eventually understand everything
Science is one of the most vast and beautiful topics to learn so please don't stop learning
Spend some extra time and start building interest towards it you will eventually be very good with science

Find a different way to process the information (visual/audible). Don't give up on the subject either. Keep looking for other options and ASK for help in understanding the subject better. Don't be afraid of failure during this process because if it is a subject you love it will pay off in the end
