PLENTY OF ENCOURAGEMENT TO TRY TO DO IT WELL, THEN!
On top of which, they couldn't really make it much easier for you : you always know exactly what to expect, and provided you have learned the vocab and grammar needed for each level, there will be no surprises.
So, pluck up your courage and here we go....
The "MARKING OUT" METHOD
I recommend that you practise this question by actually writing down the English sentence separately first, and then showing below each word its job in the sentence - a sort of 'instruction manual' to follow when you come to put the words into Latin.
This involves locating the verb before anything else, and highlighting it somehow (underline it, circle it, colour it in...). This then gives you lots of help about the nouns in the sentence: just remember that a noun in front of the verb will be the SUBJECT (NOM case), and a noun directly after the verb will be the OBJECT (ACC case).
LET'S LOOK AT A LEVEL 1 SENTENCE IN STAGES (first be sure that you do know the required vocab):
SENTENCE: The slave-girl is preparing the food.
HIGHLIGHT THE VERB: The slave-girl is preparing the food.
NOW MARK NOM & ACC: The slave girl is preparing the food.
ANSWER (with the VERB AT THE END!): ANCILLA CIBUM PARAT.
I even used to advise my old pupils to do this "marking out" actually on their exam paper - why not give yourself as much of a chance as possible?
GRAMMAR NEEDED FOR EACH LEVEL
- For LEVEL 1 you only have to know 1st & 2nd declension nouns in the Nom & Acc singular & plural, and 1st & 2nd conjugation verbs in the Present & Imperfect tenses, along with the Present tense of 'SUM'.
- Extras for LEVEL 2: as well as the above, now you also need Abl singular & plural of the same nouns (this level may now include phrases with prepositions), and the Imperfect tense of 'SUM'; you may also have a basic (-US -A -UM) adjective to put with a noun.
- LEVEL 3: now you need ALL the cases of declensions 1,2 & 3; adjectives of -US and -IS declension in all cases, to agree with the nouns; Present, Imperfect & Perfect tenses of all 4 conjugations and 'SUM'; use of prepositions; and the singular and plural Imperatives of the regular conjugations.
- In all 3 Levels, you may possibly be asked to include an adverb - these of course do not change their endings, and can just be bunged in, probably just before the verb.
HERE'S AN EXAMPLE OF A LEVEL 2 SENTENCE using the "marking out" method:
SENTENCE: The slaves were watching the tired women in the temple.
HIGHLIGHT THE VERB: The slaves were watching the tired women...
MARK NOM & ACC: The slaves were watching the tired women in the temple.
NOM pl Imperfect ACC pl
MARK THE CORRECT CASE NEEDED FOR ANY NOUN AFTER A PREPOSITION: ...in the temple.
in + ABL sing
ANSWER (VERB AT THE END!): SERVI FEMINAS FESSAS IN TEMPLO SPECTABANT.
Even at Level 2, this used to be what I would call "the easiest exercise in the book"! Nearly every time you have to make an adjective agree, you only need to put the same ending on the adjective that you have already put on the noun it agrees with (as in the sentence above: FEMINAS FESSAS).
The only times this doesn't work are if you have EITHER an -ER noun in the Nom Singular (in which case the adjective just keeps its -US ending) OR a 1st declension noun which is masculine (such as nauta or agricola). Here the adjective needs 2nd declension endings to match up with the masculine gender.
e.g. The little boy was afraid of the angry sailors.
PUER PARVUS NAUTAS IRATOS TIMEBAT.
It doesn't matter whether you put the adjective before or after the noun, although, by convention, they are usually written after it unless they have the idea of quantity (many, the rest of, sixteen.. etc.) which should go first.
HERE'S A LEVEL 3 EXAMPLE WITH "MARKING OUT":
SENTENCE: Hurry, boys! The enemy have killed the brave sailors in the market-place.
HIGHLIGHT THE VERB(S): Hurry, boys! The enemy have killed the brave sailors in the market-place.
ADD IN CASES etc.: Hurry, boys! The enemy have killed the brave sailors in the market-place.
Imperative (pl) Voc pl Nom plur Perfect ACC Plur IN + ABL sing
ANSWER (MAIN VERB AT THE END!): FESTINATE, PUERI! HOSTES NAUTAS FORTES IN FORO NECAVERUNT.
That was actually a rather harder sentence than you are really likely to get - it was chosen just to give you as many 'examples' as possible.
Making 3rd declension adjectives agree with 1st or 2nd declension nouns (or vice versa) can be a bit trickier: you can't use the "easiest exercise in the book" method, because the endings are of different types. Here you have to match case, number & gender more carefully:
e.g. Many soldiers were hurrying into the town.
MULTI MILITES....... (both words nom plur masc)
or: The sad girls are standing in the road.
PUELLAE TRISTES......... (both words nom plur fem)
or (the example above) ... the brave sailors...
NAUTAS FORTES......... (both words acc plur masc)
I suggest you re-read these examples several times, as well as the TOP TIPS.
AND, IF I HAVEN'T REMINDED YOU ENOUGH ALREADY:
PUT THE MAIN VERB AT THE END!
