These tips can easily be worth 5-10 extra points. Read through before each exam.
Review your cram sheet (key formulas only). Don't try to learn new material β just reinforce what you know. Get sleep. A rested brain recalls formulas better than an exhausted one that crammed an extra hour.
Eat something. Bring a pencil, eraser, and calculator (if allowed). Arrive 5 minutes early to settle in. No last-minute cramming β it creates panic, not confidence.
As soon as the exam starts, before reading any questions, write down the 5-10 formulas you're most worried about forgetting. This 'brain dump' frees up mental space and prevents blank-outs later.
If you have 25 problems in 120 minutes, that's ~5 minutes per problem. If a problem takes more than 6-7 minutes, mark it and move on. You can come back to it.
Pass 1: Do every problem you immediately know how to solve. Pass 2: Go back to problems you skipped but think you can work out. Pass 3: Attempt the remaining problems with whatever time is left.
If you've been staring at a problem for 3+ minutes with no progress, circle it and move on. Getting 3 easy problems right is worth more than struggling through 1 hard one.
Read the question twice. Underline the actual question β "Find the domain", "Simplify", "Solve for x", "Graph". Many wrong answers come from solving the wrong thing.
"Exact value" means don't use a calculator β leave answers as fractions or radicals. "Simplify" means reduce fully. "All solutions" means don't forget Β± or periodic solutions in trig.
If the problem says 'in the interval [0, 2Ο)', make sure your answer is in that range. If it says 'in degrees', don't give radians.
The #1 source of lost points. When distributing a negative sign, apply it to EVERY term. Double-check sign changes when moving terms across the equals sign.
If you find x = 5, plug it back in. Does it work? This takes 30 seconds and catches errors that cost full points.
Denominators can't be zero. Square roots need non-negative inputs. Log arguments must be positive. If your answer violates a domain restriction, it's extraneous β cross it out.
Know the unit circle cold. Remember: sinΒ²ΞΈ + cosΒ²ΞΈ = 1 (not sinΒ²ΞΈ + cosΒ²ΞΈ = 0). When using inverse trig, check the range of the inverse function.
Even if you can't finish a problem, write down your setup: the formula you'd use, the substitution, the first step. Many professors give 2-3 points for correct setup even if the final answer is wrong.
Start every problem by writing the relevant formula. Then substitute values. This shows the grader you know the concept, even if you make an arithmetic error.
Put a box around your final answer. Write "x = 5" not just "5". This makes it easy for the grader to find and give credit.
If you see a problem you don't recognize, skip it. Do the ones you know first. Building momentum with correct answers gives you confidence for the harder ones.
You've been studying consistently. Your brain has absorbed more than you realize. Trust your preparation. When in doubt, start writing β the steps often come back as you work.
Don't leave anything blank. An educated guess or partial setup is always better than empty space. There are no penalties for trying.
You've put in the work. Trust your preparation. πͺ
Go get that B- (or better).
