Frequently Asked Questions

For students

If I order a paper sample does that mean I'm cheating?

Not at all! There is nothing wrong with learning from samples. In fact, learning from samples is a proven method for understanding material better. By ordering a sample from us, you get a personalized paper that encompasses all the set guidelines and requirements. We encourage you to use these samples as a source of inspiration!

Why am I asked to pay a deposit in advance?

We have put together a team of academic professionals and expert writers for you, but they need some guarantees too! The deposit gives them confidence that they will be paid for their work. You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

For teachers & parents

Are you a regular online paper writing service?

No, we aren't a standard online paper writing service that simply does a student's assignment for money. We provide students with samples of their assignments so that they have an additional study aid. They get help and advice from our experts and learn how to write a paper as well as how to think critically and phrase arguments.

How can I get use of your free tools?

Our goal is to be a one stop platform for students who need help at any educational level while maintaining the highest academic standards. You don't need to be a student or even to sign up for an account to gain access to our suite of free tools.

How can I be sure that my student did not copy paste a sample ordered here?

Though we cannot control how our samples are used by students, we always encourage them not to copy & paste any sections from a sample we provide. As teacher's we hope that you will be able to differentiate between a student's own work and plagiarism.

Apr 22,  · Relay Ring Closing Metathesis (RRCM) is one of them. The first example of RRCM was reported by Hoye, as a mean to form a cyclic tetrasubtituted olefin using a first generation catalyst. 1 The first-generation Grubbs catalyst has limitations in that it is not reactive enough to directly “bite” on a trisubstituted olefin, so the ruthenium.

Apr 11,  · Living polymerization with ring opening metathesis is terminated by removing the transition metal from the end of the growing chain and its further deactivation. Deactivation in this case involves the formation of a complex unable to initiate polymerization. Ethyl vinyl ether is an effective stopper for most ruthenium catalysts. Ring-closing metathesis (RCM) refers to reactions of dienes leading to ring formation, while acyclic diene metathesis (ADMET) results in linear polymers. It is well known that RCM does not selectively proceed by cyclization of the substrate (direct RCM), but involves oligomerization followed by backbiting and concomitant RCM.[2] As a consequence. essays on time
