Use a planning range, then personalize it
The ranges below are StudyBuddy planning starting points, not rules issued by the test makers and not score guarantees. Begin by identifying the earliest application deadline that matters, then choose a test date that leaves room for score reporting and—if the test and application permit it—a possible retake. Confirm every date on the official website.
Next, complete an official diagnostic or representative practice set under realistic conditions. Review it by skill and error type. A raw score alone does not tell you whether the work is content review, strategy, pacing, stamina, or all four.
SAT: often 8–12 weeks, longer when foundations need work
The digital SAT has Reading and Writing plus Math and runs for 2 hours and 14 minutes, according to College Board. A student who is already comfortable with the tested math and reading skills may use eight to twelve focused weeks to learn the format, address specific weaknesses, and complete timed practice. Students rebuilding algebra, grammar, or reading fluency may benefit from a longer runway.
Plan around school workload and official test dates. A useful week includes targeted skill work, mixed practice, and review of every missed or guessed question. Full-length practice is important, but doing test after test without analysis can rehearse the same errors.

MCAT: commonly 3–6 months after prerequisite coursework
The MCAT covers a wide content base and asks students to apply knowledge across four multiple-choice sections. AAMC emphasizes that preparation takes time, dedication, and a plan, and provides an official content outline, study-planning guidance, and practice products written by the test developers.
Many students need three to six months of consistent preparation, but calendar length is less useful than total high-quality hours and prerequisite readiness. Starting before core science courses are understood can turn MCAT study into inefficient first-time learning. Begin with the AAMC content outline, inventory the relevant coursework, and protect the final weeks for official full-length practice and deep review.

Casper: often 3–6 weeks of format and response practice
Casper is not a content-heavy science exam. For the 2026–27 admission cycle, Acuity Insights describes a test with video-response and typed-response scenarios, with timed questions and optional breaks. Because formats can change by cycle and test type, applicants should verify the structure inside their account.
A shorter preparation window can be appropriate when it is used deliberately: learn the current format, take the official practice test, test the webcam and microphone, practise organizing balanced responses under time limits, and reflect on communication. Acuity explicitly recommends its official practice resources and warns that it is not affiliated with third-party prep services. Tutoring, if used, should focus on structured reflection and feedback—not scripts or claims to know secret scoring formulas.

LSAT: often 3–6 months, guided by timed official diagnostics
The LSAT rewards skills that improve through repeated, analytical practice: reading closely, recognizing argument structure, and reasoning under time constraints. LSAC recommends becoming familiar with the current test content and interface through official LawHub materials, and notes that timed practice helps test takers budget time and identify question types needing more work.
A three-to-six-month plan gives many students room to learn question families, practise untimed accuracy, introduce sections under time, and then complete full official PrepTests with thorough review. A student working full time or beginning far from their goal may choose a longer plan. Avoid locking in an exam date based only on optimism; use several recent practice results under realistic conditions.

Build a schedule you can repeat
- Fix the external dates: applications, score-release timing, school exams, work, travel, and accommodations requests.
- Set a baseline: use current official material where the test maker provides it.
- Divide the work: content or skill building, targeted practice, mixed timed work, and full simulations.
- Schedule review: every practice block needs time to explain misses, guesses, and slow correct answers.
- Add a buffer: illness, heavy school weeks, and plateaus are normal.
