Well, maybe probability and word problems are your weak spots
now, which isn't to say that can't change! What I like about word problems is that they simulate the reality of the types of problems pharmacists have to deal with in real life. You're much more likely to have to figure out "
If the half-life of this drug is X, how long until the patient should take their next dose?" than "
What's the inverse of f(x) = 4x - 9?" But word problems can be hard! Have you tried breaking them down to try to translate them into math expressions? For example,
Jack is 5 inches taller than twice Laura's height really just means
J = 2L + 5 once you translate it into math-speak. It gets better with practice, so don't shy away from them.
Word problems are about 50% of questions on the math section.
For probability, sometimes you'll just need to write down the appropriate probability equation, but other times it'll be easier to count it out. For example, if you were asked
What is the probability of rolling a sum of 7 when two 6-sided dice are rolled simultaneously? I would simply jot down a table with the possible rolls for die 1 and die 2 to count all the possibilities that add to 7, and then divide by the total number of possible outcomes (6 x 6 = 36). Probability problems are about 18% or 8-9 questions on the math section.
I'm glad you feel good about calculus because some people will skip over those questions when honestly they don't have to be that hard or take that long to solve. I'd say definitely try to guess on fewer than 10 questions, and if you start becoming quicker and start having time left over when you practice, get that number down as much as you can, maybe even to 5 or so. Just remember to mark the questions you guess on so you can come back to them later if you have time.
