How Long Does It Take to Prepare for the TOLC-I?

TOLC-I preparation time depends on your starting level: from 2-3 weeks for those with a good high school foundation who just need to familiarise themselves with the format, up to 3-4 months for those with significant gaps in mathematics or sciences. The decisive variable is not how many hours you study, but how you distribute them and how much you work on your specific weak areas.

"How long does it take?" is the first question everyone asks. And it is the hardest to answer without knowing where you start. For a complete overview of what to study and how to organise yourself, start from the complete TOLC-I preparation guide.

A fifth-year scientific high school student with an 8 in math needs a completely different path from a fourth-year classical high school student with a 5 in math. Same question, opposite answers. That is why THE answer does not exist — but realistic scenarios do. Let's look at them.

The factor that matters most: your math level

The decisive factor for TOLC-I preparation is your actual math level — not your school grade. The only way to know is to take a complete timed diagnostic simulation. From this diagnosis emerge three scenarios: solid foundation (2-4 weeks), specific gaps (6-10 weeks), deep gaps (3-4 months).

Not the school grade — your actual level. Which is not the same thing.

You can have a 7 in math at school and not remember how to solve a fractional inequality, because your last test on that topic was two years ago and the programme has moved on. You can have a scraped 6 but be quick with equations and systems because you enjoy them, even if you don't study.

The only way to know where you really are is to take a complete diagnostic simulation, timed, with no help. Look at the score by section — not the total — and ask yourself: where do I lose points due to not knowing the topic, and where do I lose them due to slowness or distraction?

From this diagnosis, three scenarios emerge.

Scenario A: solid foundation, need familiarity — 2-4 weeks

With a solid high school foundation (7+ in math) and a diagnostic score of 20-25/50, you need 2-4 weeks and 30-50 total hours. The realistic target is to go from 20-25 to 28-35 (+8-10 points). The main work is training for the format and speed, not studying new content.

Who you are: you attended a scientific high school with decent results (7+ in math and physics), you are in your fourth or fifth year, and on the diagnostic simulation you score 20-25 out of 50. You make mistakes mainly due to time, "rusty" topics (forgotten trigonometry, vague analytic geometry), and not knowing the test format.

What you need: not so much studying as training. The material is in your head — it is disorganized and slow.

Indicative plan:

Week 1: diagnostic simulation + targeted review of missed topics (the ones where you don't just make mistakes but genuinely don't know where to start). Usually 2-3 specific topics, like combinatorics or trigonometric equations.

Week 2: timed block exercises for each section. 10 algebra questions in 25 minutes. 5 science questions in 10 minutes. The goal is not to answer correctly — it is to answer correctly within the time.

Weeks 3-4: full timed simulations, one every 2-3 days. Error analysis after each simulation. Targeted review of topics that keep coming up as weak points.

Realistic target: from 20-25 to 28-35. Average gain: +8-10 points.

Estimated total hours: 30-50 hours distributed over 2-4 weeks.

Scenario B: specific gaps to fill — 6-10 weeks

With mixed results (5-7 in math) and a diagnostic score of 12-20/50, you need 6-10 weeks and 60-100 total hours. The realistic target is to go from 12-20 to 24-30 (+10-12 points). The main work is identifying "black holes" (unknown topics) and closing them, then training for the format.

Who you are: you went to school with mixed results (5-7 in math), or a non-scientific high school where math was less in-depth. On the diagnostic simulation you score 12-20 out of 50. You know some topics well, others you did poorly or never covered (trigonometry at classical high school, analytic geometry if the programme didn't get that far).

What you need: both content study and format training. You cannot skip to the "simulation" phase because there are topics you don't know. But you don't need to redo the entire math programme from scratch — you need to identify the holes and close them.

Indicative plan:

Weeks 1-2: diagnostic simulation + topic mapping. For each area of the CISIA syllabus (see the updated TOLC-I structure and syllabus), classify: "can do it," "rusty but I can manage with review," "black hole." The "black hole" areas are the priority.

Weeks 3-6: study weak topics. One topic at a time, theory + exercises. Here is a reasonable order for mathematics, from most to least urgent:

1. Equations and inequalities (first and second degree, fractional, with absolute value)
2. Analytic geometry (line, parabola, circle)
3. Functions and graphs (domain, transformations)
4. Trigonometry (notable values, equations)
5. Statistics and probability

In parallel, science review: mechanics, thermodynamics, electromagnetism for physics; atomic structure, bonds, stoichiometry for chemistry. Here too, start from the diagnosis: if you remember mechanics and not electromagnetism, focus on electromagnetism.

Weeks 7-10: full simulations — at least 2 per week, timed, with analysis. At this point you should know all the topics: the goal of simulations is speed, time management and response strategy.

Realistic target: from 12-20 to 24-30. Average gain: +10-12 points.

Estimated total hours: 60-100 hours distributed over 6-10 weeks.

Scenario C: deep gaps or limited high school coverage — 3-4 months

With structural math gaps and a diagnostic score below 12/50, you need 3-4 months and 120-180 total hours. The realistic target is to go from below 12 to 20-25 points — a huge jump but possible with serious work. The path starts from fundamentals (arithmetic, basic algebra) before reaching advanced syllabus topics.

Who you are: you have structural gaps in mathematics (the programme was never properly completed, or too much time has passed), you come from a technical or vocational school with little math, or you are a graduate who decided to enrol in Engineering after some years. On the diagnostic you score less than 12 out of 50. More than half the math questions leave you puzzled.

What you need: a building path, not just a review. Some concepts need to be learned from scratch, and this takes time and often external support — a tutor, a structured course, someone to explain things because YouTube videos alone aren't enough when the gap is deep.

Indicative plan:

Month 1: fundamentals. Solid arithmetic (powers, radicals, expressions), basic algebra (first-degree equations and inequalities, systems), Euclidean geometry concepts. If these are not solid, everything else collapses. There is no point studying analytic geometry if you cannot solve a linear system.

Month 2: intermediate content. Second-degree equations, second-degree and fractional inequalities, analytic geometry (line and parabola), elementary functions. In parallel, science review — basic mechanics and chemistry.

Month 3: advanced syllabus content. Circle in analytic geometry, trigonometry, composite functions, combinatorics. Block simulations (one section at a time, timed).

Month 4: intensive full simulations. 3 per week, error analysis, targeted review of areas that still give way.

Realistic target: from <12 to 20-25. The jump is enormous — but 3-4 months of serious work makes it possible. Reaching 25 means getting into most programmes without an OFA.

Estimated total hours: 120-180 hours distributed over 3-4 months.

Summary table

The three TOLC-I preparation scenarios are distinguished by diagnostic score, time needed and total hours: solid foundation (20-25/50, 2-4 weeks, 30-50h, target 28-35), specific gaps (12-20/50, 6-10 weeks, 60-100h, target 24-30), deep gaps (below 12/50, 3-4 months, 120-180h, target 20-25).

These estimates assume consistent and structured study — not "an hour here and there." 1-2 hours every day beats 6 hours on Saturday every time. For a clear idea of the financial investment beyond the time investment, check our pricing page.

When to start

The earlier you start, the better. If you are in your fourth year, preparing over the summer lets you take it in September/October of fifth year — if it goes well you are done, if not you have months to improve. If you are in fifth year and the test is a few months away, start today. The TOLC-I score is valid for 18 months from the test date.

The short answer: as early as you can.

If you are in your fourth year of high school and already know you want to do Engineering, start preparing during the summer between your fourth and fifth year. The TOLC-I score is valid for 18 months from the test date, so take the test in September or October of your fifth year — if it goes well, you're done. If it doesn't, you have months to improve and retry.

If you are in your fifth year and the test is a few months away, start today. Not tomorrow, not next Monday. Procrastinating on TOLC-I preparation is a classic — "I have finals to worry about first" — and the result is preparation compressed into the last week.

If you already have your diploma and want to enrol in Engineering, you don't have the school constraint but you have the opposite one: you are out of the study habit. Plan a gradual return — you can't do 4 hours a day from day one if you haven't studied in months.

How many simulations are needed

The absolute minimum is 5 complete timed simulations with error analysis; the ideal is 10-15 distributed across the final weeks. Quality beats quantity: 5 deeply analysed simulations are worth more than 20 rushed ones. Be careful not to "remember" answers from simulations already taken — use a large database.

There is no magic number, but there is a minimum below which preparation is incomplete.

Absolute minimum: 5 full timed simulations with error analysis.

Ideal: 10-15 simulations over the course of preparation, distributed in the final weeks.

Attention to quality: 5 simulations with detailed analysis are worth more than 15 simulations done one after another without ever stopping to understand the mistakes. Simulation without analysis is jogging — simulation with analysis is training.

The problem many students have is that they do simulations with the same questions over and over (the free CISIA practice tests have a limited database), and after a few attempts they "remember" the answers without having understood them. That is why adaptive simulations are useful: they generate different questions calibrated to your level, making "recognition" impossible and forcing genuine reasoning.

If you're not improving despite studying

If your score isn't rising after weeks of study, the likely causes are three: you are studying the wrong things (focus on weak topics, not the ones you enjoy), you are making strategy errors not knowledge errors (review the type of mistakes), or you need an outside perspective to identify the pattern you cannot see.

It happens, and it is frustrating. You study, do simulations, and the score stays the same. There are three likely causes:

You're studying the wrong things. If your weak point is analytic geometry and you spend 80% of your time on algebra "because you like it more," the score doesn't go up. Effective preparation is uncomfortable — it focuses on what you don't know, not what you already know. The most common strategy mistakes cost more points than knowledge mistakes.

You're making strategy errors, not knowledge errors. If you can solve 35 questions out of 50 but only answer 22 correctly because you manage time poorly, studying isn't the solution — strategy is. Review the errors: how many are knowledge vs. time vs. distraction?

You need someone to identify the problem. Sometimes you can't see it on your own. An outside perspective — a tutor, a study partner who is better, someone who watches you solve problems — can find the error pattern in 30 minutes that you haven't noticed in a month.

If you are in this situation, a diagnostic session with a tutor who knows the TOLC-I can unblock the preparation. You don't necessarily need months of lessons — sometimes just understanding what isn't working is enough to correct it on your own.

FAQ

Is it better to study a little every day or do long sessions on the weekend? A little every day, always. Memory and automatism are built with consistency, not marathons. 45 minutes a day for 6 days a week beats 5 hours on Saturday. Marathons work for final review, not for learning.

Can I prepare only with simulations without studying theory? It depends on your level. If you are in Scenario A, yes — simulations with error analysis are your main tool. If you are in Scenario B or C, no — you need to build the foundations first, then train. Simulations without foundations are like racing without knowing how to walk.

If I get a low score on the first attempt, how long does it take to improve for the second? It depends on why the score is low. You can retake the TOLC once a month and use the best score — so if the problem is strategy (time, avoidable errors), 2-3 weeks of targeted work is enough. If the problem is knowledge, it takes 4-8 weeks. The "once a month" rule gives you exactly this margin.

Is it worth preparing for the TOLC-I and final exams at the same time? Yes, because many topics overlap — especially math and physics. The TOLC-I covers topics through the fourth year, so test review also helps for finals. The only risk is dispersion: plan your time well and don't leave both to the last month.
