Finally...

Good news is; the problem and solving process is now challengible condition thanks to syncing the thought process.

 

And the matter is; only 'easy' difficulty level. Hopefully I can make half of it from the medium level as well.

 

Patient...don't do anything stupid.

 

current routine:

- P&S, analyse the thought process.

- P&S, attempt solving the problem. - least 20-30 mins.

- Compare and analyse 'how' it works.

- Write that solution again on a paper. - double check

- Look at the problem, and write it down without looking any solution.

(be ware not to totally memorise it. Think about the methodology to let it play the answer.)
