At techulator, the editors use pick and choose policy for the review of articles. The articles with good English and with not much of the grammatical and spelling mistakes are reviewed first than the others. The members whose articles are not selected for review must go through their articles 2-3 times to correct errors, if any. The quality articles are reviewed within 24 hours.
I cannot say how many errors you must have committed in your articles when there are errors in a single sentence you typed for your thread "its been 1 week that i have posted my article, its not yet been reviewed...."
The first words "its" should be typed as "It's or It has". The pronoun 'i' should be typed as capital 'I' whenever it appears alone in a sentence. There should be only one punctuation mark at the end of the sentence instead of tying a number of dots.
So, I kindly advise you to go through your article and correct errors, if any, before it is taken up for review.
