The paucity of time forces the applicants to think and act smart to get a higher score and succeed in the competitive exams.   Our education system is flawed in that it doesn't test the knowledge of the applicant, instead it focuses on what  one can regurgitate in a short span of time.  So as the saying goes, " In Rome, do as the Roman's do",  to succeed, one has to adopt strategies to succeed within the framework of the evaluation system.

The question is incorrect. The correct question will be, "Why is the letter R, not pronounced sometimes while speaking in English?" It becomes prudent to mention here that you cannot ask questions like these about silent letters; you have to accept them as it is. You will learn them by having somebody fluent in English, correct them or self-correct by learning the pronunciation from google.

For someone who wants to develop their vocabulary, most importantly, make a habit to state the word fully and not abbreviations or slang.  Cultivate a habit to read at least one page of text which will expose you to new words.  Find out its meaning and other information from the dictionary and study how you can incorporate it in your daily conversation. A printed dictionary or googling it will give you more information than an app. Most importantly, the pronunciation of the word is to be learnt as English is a funny language and words often do not sound as they seem to be (the word island, for example, is pronounced, "iland".  Finally, spell the words fully and not in abbreviations, in all forms of written communication to remember the correct spelling.
