Dear salam,
you are right that you have problems in EDS given your background in arts.But it is every day science and not that much boring like you may think initially.With the passage of time you find it very interesting.See question below.
1)Why it is advisable not to sleep under tree at night?
Ans)..............?
you have few option...
you may know the answer.If yes,i am sure you know EDS and what you need is to study it.
you may have friends having science as career and during gossip you can ask them few questions.
You may have good books related to EDS(which you can see in eds section of this forum) which once you are familiar with,will help you a lot.
I think the main problem is of interest,and to develop interest,study scince books of 6th,7th and 8th.They are simple and v suitable for EDS.



Now answer of the above question.

"Since you know that we need oxygen for liife.During day trees release oxygen and take in carbon di oxide gas.(photosynthesis....)
During night it take oxygen.so when we sleep under tree,there will be deficiency of oxygen and we may have problems.
