Can I prepare for the dMAT without coaching using only official materials?

Yes, you can prepare for the dMAT using only the official materials, and for learning how each task type actually works, they are genuinely enough. The instructions, worked examples, and graded exercises cover every Core Module format and the Subject Module structure in real depth.

What the Official Materials Give You

How to Fill the Practice Gap Yourself

• Once you understand the rules for figure sequences, sketch your own simple sequences and test yourself on continuing the pattern.
• Build your own small 5x5 latin squares and equation systems with two to four unknowns to get more repetitions than the official set provides.
• Ask a friend preparing alongside you to swap self-made exercises, since checking each other's logic is a useful test in itself.
• Watch the official information videos on the digital test format at d-mat.de to get comfortable with the on-screen interface.

My Advice

Start with the free official materials before you consider spending money on anything else, and judge any paid help you see advertised by one simple question: does it teach the underlying method and expand your practice volume, or does it just repackage what g.a.s.t. already gives away for free. If you cannot get a clear answer to that question, treat it as a warning sign.
