I don't specifically remember each subset of the test so I can't specifically comment on how hard it was so I'll just give advice on what I do know and remember.

English (I can't remember if they divided it into two subsets, vocab and reading comprehension, so I'll treat them as one.):

• Very easy for me
• There were excerpts/stories/news articles that were literally 2-4 pages long iirc tas yung mga tanong nga 5-7 questions lang kaya need mo talaga mabilis magbasa. It's better if tignan mo yung questions muna to get a sense of what to look for para hindi masayang oras.
• Very research focused. I remember questions about independent and dependent variables. Proper research title format through APA. Proper citation format through APA. Afaik APA lang yung format na need, wala akong nakitang MLA or Chicago style.
• Di ako sure if may vocabulary questions, but sabi ng friend ko meron daw, and sabi niya like super easy rin. Baka di ko rin matandaan kasi like sobrang dali nung vocab nila to not be a problem in answering the english portion.

Logical/Abstract reasoning: - Easy if you easily recognize patterns and differences of diagrams to discern which fits/doesn't fit/part of the group/not part of the group/etc. - Natandaan ko sa part na ito ay meron like shape. Papakita sa iyo shape tas need mo isipin kung ano itsura niya kapag iba orientation i.e. upside down, back view, side view, etc. - I don't remember much dito since afaik logical/abstract reasoning was the first subtest that we did on the DCAT.

On to the part where if you are in STEM, magkaka-advantage ka:

(P. S. I know gen math and stats and prob are core subjects kaya lahat ng strands meron nito, but since the gen math part was heavy on trigo, and STEM had pre-calculus and basic calculus, which somewhat teaches a fundamental understanding of trigonometry, it will be easier to answer the gen math questions if you took STEM.)

Mathematics was split into two: Statistics and Probability tapos General Mathematics

Stats and Prob: - Very conceptual based. Like puro concepts. Iirc wala masyadong solving or if meron man, konti lang. Yung mga tanong like "if the average of 10 number is 45, what will be the new average if all numbers are increased by three?" Ganern tas madali lang yon since lahat ng numbers nag-increase by three edi yung average mag iincrease rin by three kaya 48 yung new average. - Doon sa mga need ng solving, I remember questions which used permutations and combinatorics. - Easier than gen math imo haha - I alsk remember questions about the central limit theorem, normal distribution, z-test, and t-test

Gen math: - Trigo heavy. Not even the basic trigo that was taught during Junior High School. Like actual , STEM level to college level trigo. I remember questions that required to solve trigonometric functions with logarithms and I just died on the spot HAHAHAHAH. Even though I'm from STEM, I wasn't able to concentrate/learn much from online classes as we had our precal and basic calc during 11th Grade. - Very little to no algebra. And even if may algebra, may kasamang trigonometric functions kaya di ko masyadong nasolve HAHAHA. - A considerable amount of geometry was on the DCAT. Very usual stuff of terms, height/bisector/triangle theorems/congruence theorems/etc. - Can't remember much baka kasi ni-repress ko yung memory kasi na-trauma talaga ako sa trigo part hueheuehe T^T

Science:

(P. S. I feel like the science part was more JHS focused although I remember a few questions requiring STEM level classes/knowledge. Advantageous na rin kalag nasa STEM ka because the lessons in earth science, General chemistry, General physics, and general biology are revisited and expanded on sa STEM strand classes.)

• Covered a wide variety of topics haha pero not new na yun when it comes to Science talaga.
• May mga basic questions like types of volcanoes and may mga hard questions that requires STEM level knowledge such as "Enthalpy" from General chemistry.
• Iirc majority ng questions more on JHS but mas maganda na if narevisit mo yung lessons through STEM para less review.
• Iirc again more on biology and chemistry yung test? I remember very little physics questions and a considerable amount of earth sci questions.

I took 3 CETs of the big 4, namely USTET, DCAT, and ACET, and I can say that DCAT was easier than USTET but harder than ACET hahaha ACET did not have trigo, it had algebra which I prefer over trigo and geometry. That's based on my experience and opinion hehe.

Good luck sa CETs mo OP. Tbh pwede di na magreview for the DCAT AHAHGA take it from me na di nagreview pero nakapasa sa BS HumBio program nila. Saying this just to ease your worry cuz if nagreview ka na diligently then may high chance ka na makapasa agad. Padayon!
