The Exam Success Guide

What to use,
when to use it, 
and how to support your child through every paper.

See what to use

Your child does the studying. You can carry the rest.

The past papers are stacked on the desk and the timetable is up on the fridge. 

Between now and their last exam, the work is theirs to do. Everything around it is where you can support them: how well they sleep, whether they eat before a paper, and how they hold up as the pressure builds.

Here is what exam pressure tends to look like, and how you can support your child through each one.

Three signs to watch for

Teenager with her hand over her mouth, distracted while studying

Focus fades an hour into studying

What it looks like: Your child sits down ready to work, and an hour later nothing on the page is going in.

What’s happening: Long study days draw on the building blocks the brain uses to make its focus and motivation messengers, and under sustained effort they run down faster than the body replaces them.

Support them with Learnergy™: It supplies those building blocks along with slow-release brain energy, so focus lasts through a long session.

They know the work, then freeze in the paper

What it looks like: The revision was done and the answers were there the night before, yet in the exam hall the mind goes blank.

What’s happening: Freezing is the nervous system’s response to pressure, and it can happen to the best-prepared child.

Support them with Relaxify™: It supports nervous system regulation with L-Theanine, GABA and magnesium, helping your child stay steady and composed in the paper.

Wide awake the night before a paper

What it looks like: The books are closed and the light is off, and your child is still lying awake running through tomorrow’s paper.

What’s happening: Sleep is when the brain stores what was studied that day, which makes the night before a paper part of the preparation.

Support them with SuperSleep™: A non-sedative night-time formula. Taken every night, it helps your child fall asleep faster and wake up without grogginess.

Hot or cold 30 minutes before bed

We started using SuperSleep at the beginning of my daughter's mid-year exam period, when the combination of studying, stress, and maintaining her usual activities was taking its toll. From the very first night, we noticed a difference. She woke up feeling genuinely refreshed and well-rested, which made a noticeable difference to her energy and focus during the day. It has become a valuable part of my daughters evening routine and it's refreshing to find a product that supports better sleep without leaving her feeling groggy the next morning.

5 study habits that work

These habits make the studying itself go further, and each one is something you can help with.

  1. Swap re-reading for self-testing.

    Re-reading feels productive, yet recalling from a blank page is what makes information stick. In one well-known study, students who tested themselves remembered about 80%
    a week later, against roughly a third
    for those who kept re-reading. Offer
    to quiz your child from their notes.

  2. Spread it out.

    Three one-hour sessions move more into long-term memory than one three-hour sitting. Help your child plan each subject over several days.

  3. Ask them to teach you.

    Explaining a topic out loud shows up the gaps before the paper does. Ask for a five-minute lesson over supper.

  4. Mix the subjects.

    Switching between subjects in one session can help the brain link ideas, and it mirrors the way exam questions jump around.

  5. Set a books-closed time.

    Sleep is when the day’s studying is stored, so agree on a time the books close each night.

A small investment now goes a long way over the exam period.

There's a flavour for every taste, and if your child is fussy, the unflavoured options slip easily into their favourite drink.

My kids love the Learnergy, they enjoy the flavor, and say it definitely helps with concentration and fuels them for studying or their exam.

Learnergy™ has 20 servings, ClariBoost™ has 30 servings, and Relaxify™ and SuperSleep™ have 30 each.

At one serving a day, Relaxify™ and SuperSleep™ last a full month, while Learnergy™ and ClariBoost™ run out a little sooner. Exams run for several weeks, so plan a Learnergy™ or ClariBoost™ top-up partway through the exam period.

Beyond the Trios

The Trios covers the three things exams test hardest, but exam season asks more of a child than that. Appetite drops, routines slip, and a run-down body is quicker to catch whatever is going around. The products below sit alongside for the rest of what finals wear down.

The foundation

Long study days, short nights and exam nerves put strain on more than focus. 

Mood, digestion and immunity all feel it, and that’s when a child gets run down.

For mood, gut and immunity under exam strain

SuperTonic Boost & Strengthen tub

The 5-in-1 daily foundation that sits underneath the Study Trio.

  • One daily drink that supports mood, gut and immunity through the exam period
  • Supports stress resilience while the pressure is on
  • Prebiotic fibre and a probiotic for digestive comfort
  • Vitamin C, Zinc and Vitamin D3 for immune resilience when your child is run down
  • Full daily vitamins and minerals, with no added sugar

  • L-Glycine (1.8g), GABA (100mg) and L-Theanine (100mg): support emotional balance under pressure
  • Myo-Inositol (250mg): supports mood regulation
  • L-Glutamine (2g): supports the gut lining and immune cells
  • Fibersol®-2 (3.1g) and LactoSpore® (500 million spores): prebiotic fibre and a probiotic for gut health
  • Vitamin C (1000mg), Zinc (25mg) and Vitamin D3 (15mcg): immune defence
  • Methylated B-Vitamins: for energy and mood, in forms the body absorbs easily

One scoop in 250 to 300ml of cold water, once a day.

My daughter used this every day during the stressful exam and winter months. It helped keep her healthy and focused to continue on with her very busy schedule.

Eating through exams?

Nerves can take the edge off an appetite, and meals are often the first thing to go, whether it’s breakfast before a paper or lunch in the middle of a long study day. 

A paper can run for three hours and a study session even longer, and both are easier on a child who has eaten. Keep exam-day food simple and familiar.

For the meals that exam days push out

MaxiMeal Complete Meal Shake pouch, Salted Caramel & Popcorn flavour

A complete meal shake for the mornings and study days when a full meal isn’t realistic.

  • A complete meal with that covers the meals finals tend to push out: breakfast before a paper, lunch during a long study block, or supper after a late session
  • Still goes down easily on the days nerves take away your child’s appetite
  • Protein and low-GI carbohydrates for steady energy and focus that lasts through a paper
  • Healthy fats from coconut, which the body turns quickly into fuel for the brain
  • Probiotics and digestive enzymes, for digestive and gut health so it sits well on a busy or nervous stomach

  • Skim Milk: whey and casein protein to keep your child full for longer
  • Palatinose® and Waxy Maize Starch: low-GI carbohydrates for steady energy
  • Coconut MCTs: healthy fats the body turns quickly into fuel
  • Fibersol®-2 and Nutriose®: prebiotic fibre for digestion
  • LactoSpore®: a probiotic for gut health
  • DigeZyme®: digestive enzymes to help absorb more from every serving
  • Vitamins and minerals - 50% NRVs

Four scoops pouch/one sachet (60g) in 250ml of cold water, or (30g) in 250ml of milk.

Have it at breakfast before a paper, or whenever a meal gets skipped.

MaxiMeal™ sits alongside regular meals.

My kids struggle to eat in the morning and love having this easy, nourishing meal. The Relaxify is a staple in our house and is a must before big competitions and exams and it even helps them sleep better. Can highly recommend.
