i don't agree with a lot of these post regarding the teas test. if they are really taking the teas and only taking the reading and english portion, then that is not the teas -- sounds more like the tabe or general test for reading comprehension/level of reading.
i just took the teas and it was hard. i studied for two months prior and still thought it was difficult. my test had reading, english grammer, spelling, math and science - covering biology, anatomy & physiology, chemistry and some physics! now, i've taken all of these subjects in high school (28 yrs ago) and took a & p and micro most recently at the 3rd year college level courses. i have to say, the questions on my test were mainly chemistry and physics questions. not sure if that holds true for all teas tests, as they pull random questions for all.
my advice is to buy a study guide and study! i scored 95% overall, but barely. had i not studied, i probably would have come more closely to a 70% or failing score. any nursing exam book will do that covers all the basic sciences, math - to include algebra, precentages, ratios, fractions, statistics and geometry w/very little trig type questions. (for the record - i scored 100% on the math portion) make sure you know all formulas you learned in high school too ... without that review, i would have bombed the math portion. forgot to mention, there is also a lot of metric conversion -- like "a patient weighs 150 pounds, how many kg does the patient weigh?" if you don't remember the forumla; 2.2 lbs = 1 kg - you'd be screwed on the exam!
that's my best advice to you. i purchased a book at borders for less than $25 that has practice exams that you actually take on the computer, timed and results that follow with incorrect answers explained. that saved my "you know what" in the end as well.
also, if you register at atitestin.com, you can take a practice assessment - not the same as the "practice exam" offered with like 20 questions/answers - but more like the real test.
good luck to you
