Got 680- journey has to be on

did you take 8 mins only to Read The RC or 8 mins to complete a long RC? If you take 8 mins to complete (read+ finish the questions ) for a long passage you are well within the mark .... if not (if you take 8 mins to read only ) then you need to change few things ...

do you take notes while you are reading the passage ? if yes this might be slowing you down ..... contrary to the advice by few instructors or test companies preparing people for gmat i will advice not to take notes while reading passage .... read the passage as if you are reading a executive summary of the project .... having idea of where details are ... (later on if the question that follows asks a specific detail - you know where to look back .... it is ok if you have an idea that certain detail is to be found in paragraph 2- line -3 and instead they appear on line 5 or 6 of the paragraph 2 ... you can easily read three lines in 10- 15 seconds in second reading .... taking notes will push you back by 2 - 3 mins or more every paragraph ) ... This way you can save time .. else always you will be shortage of time ..(i agree tough that some hit on accuracy might be there if you follow this still better than not completing the test on time or getting a poor result .)

Just keep in mind that for specific question that require detail you will read the relevant lines again before you answer the question .... for questions like main theme or main purpose etc (global questions i meant ) first reading is enough ....

try doing this with RC questions from GPrep . On this forum the entire gprep question bank is available .... the RC question bank of GPrep has more than 100 passages .... solving question from Gprep will help you in staying as close to the real question as it can get ....
Take a note of timings of every passage that you read , noting every time the time to took to read + time you took to complete the passage (both for long passage and also short passage ) ... after solving some 50- 60 such passage you will have a good grip ... (aim for 2 mins of reading time and at max 6 mins to complete short passages that generally have 3 questions and for long passages 3 mins for reading and additional 5 mins to complete 4 questions so a total of 8 mins at max ) but all of this only after you have solved 50- 60 passages from gprep question bank .....

Since there are more than 100 passages you will not remember much after you solved all (this might take care of repeats when you write gprep exam again) ... while you write gprep after all of this exercise ... make a habit of subtracting 6 mins from the time as soon as a short passage were to appear ... and 8 min for a long passage ... if you are crossing this time limit and say by that time you solved only 2 out of 4 questions then guess the other two question .... because the test is made in such a manner that the penalty for leaving the test unfinished is huge and even if you rush and some how finish the test on time ... you would fall in some trap that gmat sets in its questions .... again for this too penalty is huge ... the penalty is small only for missing out on tough question (contrary to what people think ... getting 700 means solving most 700 level question- a big no ) ....

For CR try reading the CR powerscore bible ......... then solve at least 50- 60 LSAT CR questions ..... and then solve the entire gprep question bank of CR ... i guess there are close to 150 CR questions there ... This way you will be taking care of CR and the RC part in this attempt.

I have attached the RC question bank of gprep . I wish you all the best in future endeavors.
