Short, practical reference material for the four skills covered on SkillNest — grammar, vocabulary, typing and general study technique.

Study habits that actually work

  • Short and regular beats long and rare. Fifteen minutes a day builds far more than two hours once a month.
  • Test yourself. Reading a rule feels productive; recalling it without looking is what makes it stick.
  • Space your review. Look at a rule again after one day, then three, then a week.
  • Learn in sentences, not lists. A word you met in a sentence is easier to use than a word from a list.
  • Keep an error log. Write down what you got wrong and why. The same mistakes repeat until you write them down.

Grammar quick reference

A few rules that come up again and again in the tests.

for vs since

for + a length of time (for two hours, for six years). since + a starting point (since 2015, since Monday).

fewer vs less

fewer with countable nouns (fewer chairs, fewer mistakes). less with uncountable nouns (less water, less time).

Prepositions of time and place

Subject-verb agreement traps

  • Words like news, information, advice look plural but are singular: the news is good.
  • Each / every one / neither take a singular verb: each of them has.
  • With either … or / neither … nor, the verb agrees with the subject nearest to it: neither Tom nor his brothers are coming.

Commonly confused words

WordsMeaningExample
affect / effectaffect = verb, to influence · effect = noun, a result The rain affected the match. It had no effect on the score.
its / it'sits = belonging to it · it's = it is The dog wagged its tail. It's raining.
your / you'reyour = belonging to you · you're = you are Is this your book? You're early.
there / their / they'replace · belonging to them · they are Put it there. Their bags are ready. They're here.
then / thanthen = at that time · than = comparison Finish this, then rest. Taller than me.
rise / raiserise = go up on its own · raise = lift something Prices rose. They raised prices.
accept / exceptaccept = receive · except = not including I accept your offer. Everyone except me.

Building vocabulary

  • Learn word families. From rely you get reliable, reliably, reliability and reliance — five words for the price of one.
  • Meet words in context. Note the sentence you found the word in, not just the definition.
  • Use each new word within a day. Write a sentence, say it aloud, or message a friend with it.
  • Group by topic. Ten words about work, ten about food, ten about travel are easier to recall than thirty random ones.

Typing technique

  • Home row first. Rest your fingers on A S D F and J K L ; and return there after every key.
  • Accuracy before speed. Speed follows accuracy, not the other way round. Aim for zero errors at a comfortable pace, then push the pace.
  • Sit upright, wrists neutral. Keep your elbows close to your body and your wrists straight rather than bent upwards.
  • Look at the screen. Train by touch — it feels slower for a week and then it is much faster.
  • Measure, don't guess. Take the typing test once a week and compare numbers, not feelings.
