Se conjugations
I've been having trouble conjugating "Se". Could I get help? I do know that it is improper... or something like that, but I don't know how you change it.

Your question is not entirely clear.
If you are asking how to conjugate the verb saber (which is an irregular verb), to know here is the conjugation:
http://www.spanishdict.com/conjugate/saber
And I will quote the present indicative forms:
yo sé
tú sabes
él/ella/Ud. sabe
nosotros sabemos
vosotros sabéis
ellos/ellas/Uds. saben
If you are talking about conjugating verbs with the reflexive pronoun se here is our lesson:

And a quote with how the pronouns change:
Singular Plural
1st person me (to, for, from, or off myself) nos (to, for, from, or off ourselves)
2nd person te (to, for, from, or off yourself) os (to, for, from, or off yourselves)
3rd person se (to, for, from, or off himself, herself, itself, yourself) se (to, for, from, or off themselves, yourselves)
If it is something else, I am not able to guess it.
The many uses of 'se' can be very confusing and sometimes. I find myself struggling with it still, but I've found a way to turn the muddy mess into a system. I like to distinguish 8 types of 'se':
1. Se variante contextual de le(s) When 2 pronouns (first of the indirect object, then of the direct object) follow each other up, and both refer to the third person (singular or plural) (indirect = le(s), direct = lo(s), la(s)), the first (le(s)) is replaced by 'se'.
"*Le lo voy a decir a él." --> "Se lo voy a decir a él." = I am going to tell him about it.
2. Se impersonal This is for very general expressions and often refers to an unidentified or not very specific group (of people). (it's always in singular!)
"Se bebe mucho aquí." = People here drink a lot.
3. Se pasivo-reflejo This is for phrases in the 'voz pasiva' in which the subject is unknown (the bank was robbed *by someone unidentified!), can be logically derived from the context (the robber was arrested *by the police) or just if you'd like your public to pay more attention to the object or verb and less to the subject (the robber's twin was given many funny looks on the streets)
"Muchas casas bonitas son vendidas este año." --> "Se venden muchas casas bonitas este año." (Many beautiful houses were sold this year.(The first is more likely to provoke the question: by whom?))
The first 3 types of 'se' DO NOT conjugate. The following 5 DO, like this:
yo->me_ tú->te_ él, ella, usted, ellos, ellas, ustedes->se_ nosotros/as->nos_ vosotros/as->os
4. Se reflexivo This is used when someone or something does something to him/her/itself.
"Él se lava." = He washes himself or "Yo me lavo." vs. "La enfermera ducha al paciente." = The nurse washes the patient.
5. Se recíproco This is used to show that two agents do the same thing to one another (so the verb is always in plural!)
"Esas modelos se odian la una a la otra en secreto." = Those models secretly hate each other. "Nosotros nos queremos." = We love each other.
6. Se télico This one can be added to indicate that an action has been completed.
"Mi novio comió su cena." = My boyfriend ate his dinner. (if he finished it is unknown)
vs. "Mi novio se comió su cena." = My boyfriend at all of his dinner. (no doggy bag tonight!), or for the sake of conjugation: "Yo me comí todo el turrón, mmm~.. "
7. Se medio This one is used for the 'voz media', which hovers somewhere between the active and passive voice and I think is best explained through some examples:
voz activa: "El enemigo hundió el barco." = 'the enemy sunk the boat' voz pasiva: "El barco fue hundido (por el enemigo)." = 'the boat was sank (by the enemy)' voz media: "El barco se hundió." = 'the boat sank' This one is rarely ever conjugated because it tends to make for really weird phrases, but it is a possibility, such as: "Me estoy muriendo..." = I am dying...
8. Se léxico There are 2 options here: se léxico inherente (for verbs that always have se, it's simply part of the verb and cannot be used without it) & se léxico opcional (for verbs that can be used with or without se, which creates 2 different verbs although their meanings are usually related)
inherente: "Ella siempre se jacta de su talento para la natación." -> She always boasts about her talent for swimming."
opcional: ir vs. irse: "¡Vamos a la playa! :D" vs. "¡Véte de aquí, perverso! 
"
Both of these conjugate and I'm sure you've encountered examples of them doing so before. 
It is and stays a complicated subject, but I hope this gives you a bit of an overview. Sometimes it can be next to impossible to tell which type of se is used. If need be, context is key. Don't worry though, usually it's not necessary at all to classify them, it's just good to know the possibilities, so that you know of the possible implications of meaning and to not feel so lost as to what that 'se' could possibly be doing there!
